Errors after upgrading to SIM v5.0 SP3

[Chuck Gasaway]

I recently upgraded from CIM 7 to HP SIM 4.2 without any problems. Once that stablized I went on to upgrade to SIM 5.0 SP3. Now the problems. Can not see any of the servers that are managed even though they are listed when clicking on the 'all managed systems' link under authorizations, there are no automatic tasks. Also get an error when attempting to go into the 'Customize Collections' option. Error is: "Cannot load custimization page due to an internal error".
It's beginning to look like I should have stayed at v4.2.
Any ideas? Thanks
