I have a site that uses both forms and windows authentication. Both of the windows auth site and the extended forms auth are created and working. Anonymous access is working in both places as well. The solution can be added, but when I go to activate it, i get this error: "Failed to instantiate file "AdminWebPart.webpart" from module "UserAdminWebParts": The specified list does not exist".

Has anyone seen this error before?

It turned out to be some sort of corruption in the site collection as no solutions could be activated. Ultimately, the solution was to create a new site collection and rebuild.
