A lot of threads are already dealing with this and have (possible) solutions.

About the “usigetskin failed” issue, if the 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:
C:\WINDOWS\SYSTEM32\REGSVR32.EXE ACTSKIN4.OCX
Press OK (or Enter).
A message saying that the file was successfully registered should appear…
