DreamWeaver (CS5) so far works just fine, although I haven't been doing anything with power CMS lately. It's just a bother to have to click ok in the error msg dialogue box every time I open DW.
I deleted my Windows Data Cache file, per the instructions in the "common installation issues" document, but that didn't change anything. I have so many extensions installed, I am loathe to uninstall and reinstall all of them.
Any suggestions about what might be causing this error message and how I can fix/get rid of it?
