Contribute seems to have trashed my DW

I used "Contribute" trial version and a colleague was the "Admin". Some glitch
occurred after I posted and now I can't use my DreamWeaver 4 or UltraDev 4 (for
Windows 98 SE) any longer. Macromedia does not support these versions anymore
supposedly!

Can anyone help?

check this technote
http://www.macromedia.com/support/contribute/ts/documents/dw4_crash.htm

there's a work-around in the technote, but if you don't set up Dw4 just
right to prevent the Design notes sharing, the .mno files from MX 2004 will
cause Dw4 to totally lock up.
