I'm trying to create a Role that requires a Paypal Payment for a user to become a member of it.  I'm running into errors and not sure if its because of my upgrade from 4.9->5.01 or something else.

I can subscribe to a free role fine.  If I click subscribe to a paid one, I am getting redirected to home page and the following error is occuring.  The 5.01 database upgrade script did error with "System.Data.SqlClient.SqlException: Table 'EventLog' already has a primary key defined on it. Could not create constraint." however I understood from previous reports this shouldn't impact functionality.  Any ideas?
