Are you sure?!
Thanks Dani - I tried the winfilecache delete to no avail. Are you surte about the Configuration folder delete? It sounds like it will uninstall all of my installed extensions and then need to reinstall them which represents hours of work!
Craig - I tried to roll back to version 3.0.6 but it crashed DW CS4 each time I tried to open UE.
Something is truly messed up and I can not afford the lost time!
Thanks for both of your responses. I'll give it a shot and hope it works. Will post back my results.
