My Avast Can't Open!!!

Everytime I try to open it, I get an error message stating: “unknown error message”, “Application cannot load skin. Function usiGetSkin Failed”.
I even tried typing this into START → RUN
C:\WINDOWS\SYSTEM32\REGSVR32.EXE ACTSKIN4.OCX
for my windows xp, but it doesnt work.
I get the error message: “DllRegisterServer in ACTSKIN4.OCX failed.”

Someone please help me.

About the “usigetskin failed” issue, if the avast! repair does not solve it:
You will have to register ACTSKIN4.OCX
Follow the instructions:

Select START → RUN…
Enter the following command:
If you have Windows NT or 2000:
C:\WINNT\SYSTEM32\REGSVR32.EXE ACTSKIN4.OCX
If you have Windows 95, 98 or ME:
C:\WINDOWS\SYSTEM\REGSVR32.EXE ACTSKIN4.OCX
If you have Windows XP/Vista:
C:\WINDOWS\SYSTEM32\REGSVR32.EXE ACTSKIN4.OCX
If you have Windows XP/Vista x64:
“C:\WINDOWS\SysWOW64\REGSVR32.EXE” ACTSKIN4.OCX
Press OK (or Enter).
A message saying that the file was successfully registered should appear…
