I got the same error you did, but I'm on a mac. I can't find that file you had to delete. What should I do?
I just wanted to let you all know that my problem has been solved.
I posted a Trouble Ticket early this morning, 8 May 2009.
I received a message from Jason Byrnes, at 02:13 PM on 8 May 2009 suggesting I try deleting the WinFilecache-########.dat
It worked. I am back in business.
BTW, I checked my download folder and CSS Sculptor 2.0.3 was still listed early this morning.
Thanks again and have a great weekend everyone.
