I just had a similar error appear in DW CS4. I get these two error messages (see images below). I followed the advice given, deleted a WinFileCache-3012BA81 file in my Configuration folder, and it did not help. I also cannot "cut & paste" now in DW. Any new updated suggestions? It would be very much appreciated. Thank you!
Thank you, I found another thread answer that helped: I had to close DW while I deleted the Win.dat file; then it worked.
