Once your logged in, open My Computer, find: c:\documents and settings\<your username>

Right click on the folder and select properties, then click the security tab, then click Advanced, then on the owner tab, select your name, tick the "Take ownership of all subfolders and files" then click apply.

Once done log off and back on again and see if the problem is gone.
