Slow logon and CSC folder too large

Hi,

When I log into my machine on XP pro it is taking over 10 minutes to log in
and get to the desktop. I've just had a clear out and I can see the CSC
folder is >10Gb. I've also checked the contents of "My Documents" and I can
see there are another 9 total copies of "My Documents" copied inside one
another.

Is there any way I can stop this from happening and also clear out my
bloated CSC folder? I have a suspicion the two problems are related.

Thanks.
