I'm having a really strange problem with Hammer. Whenever I try to save a file it only allows it to save to C:\Users with a custom name, otherwise it will save as "C:\Users\Default.vmf". If I don't run it as an admin, I get this message: "You don't have permission to save in this location. Contact the administrator to obtain permission.", but I am the administrator. And if I try to overwrite the file I get this message: "Hammer was unable to backup the existing file "C:\Users\Default.vmf" (Error 0x5). Please verify that there is space on the hard drive and that the path still exists.", I have 280GB free. The last time I used Hammer (a few months back) everything was fine and not much has changed: same PC, same OS. Please help me.
