At first, I got these errors upon logging in to GP. Deleting ACTIVITY and all of those usual suspects did not work.
So, I fixed this by logging into GP as "sa" and checked to recreate the auto procedures for Posting Definitions Master in SQL Maintenance.
Now, upon logging into GP, I'm getting a GPS Error: 56 and a message saying that RM00101 is an invalid object name.
Please help!
