unable to write a necessary file

[jberylec]

Running Vista Ultimate. I am the Administrator.

Downloaded LimeWire right from the site. Online install, no errors during install.

When launching LimeWire it does launch in the glass aero, but I got the following error many times...

"LimeWire was unable to write a necessary file because you do not have the necessary permissions. Your preferences may not be maintained the next time you start LimeWire, or LimeWire may behave in unexpected ways."

LimeWire seems to connect and allow downloads, however the error popup is very annoying. And sure enough it's not saving any settings/preferences.

So I completely uninstall LimeWire and Java. Rebooted. Reinstalled everything in the same exact way, using LimeWire's online installer for Windows.

Now it launches and Vista switches out of Aero mode because it states that LimeWire isn't compatible with it. I dont get it? The Aero was working before! Anyhow, I'm still getting the above error popups constantly.

Help!?
