I find myself having to reinstall Photoshop Elements every month or so because after a while, everytime I load it, I get the following Bad Image message:

C:\ProgramFiles\CommonFiles\Adobe\Web\AdobeWeb.dll is not a valid Windows image. Please check this against your installation diskette.

Photoshop still loads and works (barely) if I hit OK twice and keep going.

I use XP. Could this be the problem and how do I fix it?
