Can't run Fantasy Grounds on Vista

[Mal]

I had been running Fantasy Grounds on Vista with no problems when I began receiving file transfer errors at the beginning of every gaming session. They would last for at least a half hour. I decided to uninstall and re-install fantasy grounds to see if that would clear things up and now it won't run at all. My computer is telling me that Fantasy Grounds is not a valid win32 application and will not run. I know it should run, because it used to run fine except for the extensive error messages that scrolled across the chat log when I would first sign on. When I ran the update for the first time after running the install I did receive an 'error processing package list' message. But after starting the update back up it seemed to finish updating with no further problems until I actually tried to run the program and got the not valid win32 app message.

Any ideas on what could be causing these errors?

Along with an uninstall/reinstall, it may be worth removing or renaming your Fantasy Grounds II folder under your {username}\appdata\Roaming\ folders. If it works with the basic items there, try adding back individual rulesets, mods and ext files one at a time.
