1st are you using Fullglass.exe or Black Glass Enhanced with these themes if so close them.
2nd try removing Glass 7 out of C:\Windows\Resources\Themes put it on your desktop for now
restart & check if that worked.
If not try this
SFC /SCANNOW : Run in Command Prompt at Boot if you are using universal theme patcher you will need to run it again after the sfc /scannow
see if that helped.
