Hi and thanks for getting back to me -
Here is the exact error message:
I followed these procedures:
1. Closed Dreamweaver
Deleted the MacFileCache.dat file (when I reloaded CSS Menu Writer, that file never reappeared).
2. Deleted the config. folder/renamed it/uninstalled extension.
3. Re-installed extension.
Then, I got the same error message.
Would appreciate any help that you can offer!!
