Maya startup error - Fatal error. Attempting to save in
C:/Users/MyUser/AppData/Local/Temp/MyUser.20130818.2028.ma"

I have a problem with Autodesk Maya 2014. All the time when I open it I
get this error: "Fatal error. Attempting to save in
C:/Users/Remus/AppData/Local/Temp/Remus.20130818.2028.ma" What I have done
until now:
I removed Maya preferences folder form my Documents
I reinstalled Maya.
I run a RAM test and I get no errors
I removed everything from Temp folder.
I am using Windows 7 x64. The program worked for 2,3 months.
Can you help me, please?
