I am having the same problem with one of my users. Thanks for the info enuffsaid, I followed the links and tried the steps suggested. When doing a search for the .nk2 file extension (searching *.nk2) it is not returning any results. No files with the .nk2 extension. I am searching through all hidden files and folders, and have checked under the application data folder and am still not finding anything. I even tried creating the file, calling it profilename.nk2. Still no good. Any other suggestions? Thanks.
