Vista - Foldershare Account Hacked

I am a FolderShare user and I logged in to my account and noticed a computer
that is not one of mine. I am concerned about what data they were able to
get. I have remote browsing turned off on my other pcs but they could have
synced with one my libraries. I checked my local FolderShare log file and
was not able to decipher any meaningful information. Is there any logs to
see if they synced with one of my libraries and what was actually synced?

Any help you can provide would be much appreciated.

Thanks,
Ryan
