Vista - Need Help - .XML files - permissions - read/write

Hello,

First time on this forum, so I hope I chose the right category to post my problem. I just got a new laptop, and it has Vista Home Premium.

My problem.. I use a program/application called "DVArchive" (aka: DVA) for archiving my tv shows on my PC (from my ReplayTV). This application worked just fine on XP, but of course, Vista is giving me all kinds of crap.

The application IS working.. It can see my ReplayTV unit, I can access my archived shows, etc. However, Vista is giving me error messages, which are interfering with it and making it crash.

The problem has to do specifically with the applications configuration (.XML) files. I'm pretty tech saavy, but I'm not a computer expert, so I'll just cut and paste the actual error messages below. The listed pathways are where DVArchive stores it's files...

Basically, it looks like Vista is not allowing this app to copy/backup these .XML files. I've been trying things like disabling UAC, changing ownership and editing permissions on files, etc, but not with much luck. And, I get no option under properties for "Compatibility" (no tab), or "Run as Administrator" (option is greyed out). The DVArchive runs on an executable .jar file.

I'm a novice. Ownership/Permissions tampering is all new to me. I don't want to do anything too drastic without some help from more knowledgable people. The one error I keep getting is the third one, "Unable to rename old store (DVArchive.xml to DVArchive.xml~) - Please be sure the directory/file can be read/written to".. that's the one error I always get.

I'm really hoping someone can help me solve this problem.

Thank you,

Zack
