I then again, did uninstall and reinstall of windows live messenger, baught regcure, it fixed a bunch of errors, then tried windows live messenger again, and it DID work.. sooooo I thought, good ohhh

getting to the point where I just want to reformat my laptop..

oh yes, am using vista home premium

This stupid issue pissed me off recently and i tried many diff things.

Anyway, the least mentioned about method worked for me, so give it a try.

Restart your router/modem.
Software restart worked for me, but also try pull-the-plug and re-plug routine, if software fails.
And restart the computer (if you havn't already done so a dozen times)

Troubleshotting:

1. First of all, make sure you have the latest version of Windows Live Messenger. Download the latest version here.
2. Check the date on your computer. 8100030d can be caused by wrong date on your computer.
3. Disable any firewall program such as ZoneAlarm, Norton Internet Security and etc. Reboot and try connecting again. Sometimes even after disabling firewall, it will still block your connection. Try uninstalling to verify that firewall isn’t causing the problem.
4. Check your Internet Explorer LAN settings. Open Internet Explorer, go to Tools > Internet Options > Connections tab > LAN Settings. If you’re not connecting using proxy, make sure that use proxy server is unchecked.
5. Check your Internet Explorer Security settings. Open Internet Explorer, go to Tools > Internet Options, Advanced tab, scroll to the Security section, and verify that “Check for server certificate revocation” is unchecked. Also verify that ‘Use SSL 2.0′ and Use SSL 3.0′ is checked.
6. Make sure Windows Live Messenger DLL are registered. Click Start, then Run, and enter the following command one by one and click OK.

regsvr32 softpub.dll
regsvr32 wintrust.dll
regsvr32 initpki.dll
regsvr32 MSXML3.dll

7. Delete the cache for Windows Live Messenger. Browse to the folder below and delete all files and folder inside them:

For Windows XP
C:\Documents and Settings\Username\Contacts\Messenger email
C:\Documents and Settings\Username\Local Settings\Application Data\Microsoft\Windows Live Contacts\Messenger Email For Windows Vista
C:\Users\Username\Contacts\Messenger email
C:\Users\Username\AppData\Local\Microsoft\Windows Live Contacts\Messenger email

8. Reset your router. Power it off, wait for 2 minutes and turn it back on.
9. Try to connect to the Internet using another router, modem or even try to use cellular GRPS/3G connection to connect to the Internet. Then try to connect to Windows Live Messenger again.
10. Scan your computer for virus and spyware. It might be some nasty virus hijacking your Windows Live Messenger.
My friend’s Windows Live Messenger was able to connect from his computer after I’ve changed the existing router. I’m not sure why can a router be causing 8100030d error during Windows Live Messenger sign in… but if it is, you can try updating your router’s firmware first before throwing it away. Hope one of the solution above is able to help you connect to Windows Live Messenger without getting 8100030d error.

Yeh i went through all those things, pretty much in that order too
got up to 8 and it was all fixed.

I also read somewhere mentioning that it might be some Netgear modems my being the DG834G, don't really want to change the firmware on it, as it was having stabilisation issues before with diff firmware editions
