eOne Extender - New solutions do not import correctly. Old solutions do not delete properly.

I had experienced problems loading new solutions even after deleting old solutions.
I resolved the issue by running the grant.sql on all databases, and then manually going into the extender tables and deleting any data i found in them pertaining to the old solutions.

Once the tables were cleared out, the new solution imported correctly.
