personal computer_Logging to temp profile_ lost my admin rights

Hello,
I am in a dire state of problem. I am using windows 7 ultimate on my Dell inspiron N4010. I have been logged on to a temp profile by which I understand that the user profile i am using is corrupt. I went to <regedit> and deleted the ".bak" extension from file. This did not fix my problem. I then created another account and transferred all my file to the new user account except ntuser.dat.LOG1, NTUSER.DAT and ntuser.dat.log2.
After all my files were transferred, I gave admin rights to the new profile and made my corrupt or current profile a standard user profile. I logged off my corrupt profile and when I was logging on to my new profile it says " The group Policy Client service failed the logon. Access is denied.
Please help !!! I have tried using command prompt to create another admin profile, another user profile, to activate in-built admin and other methods from different forums and youtube. Nothing has worked. The problem seems to be that I am unable to do anything because of the temp profile. What can I do ?

Hi Shawn,

My only concern while deleteing the corrupt user profile is that, will i still be able to log on to the computer? Since the group standard policy is not allowing me to logon to my admin account. In addition, with my current user profile i am unable to create another user profile.
