ReportingRefresh Job continues to fail.

My Report results were starting to get out of sync with PWA results so decided to do a rebuild of the project server reporting database to see if this cleared the issue.  I've done it a couple of time and it seemed to correct the problem.  This last time I tried it it failed and continued to fail after trying a couple more times.  I keep getting this message;

Your ReportingRefresh job failed.  Its current state is FailedNotBlocking. It was 0% complete.  It entered the queue at 06/26/2012 17:40:34.

To get more information about the job failure, please go to Project Web App. Select Personal Settings from the left menu.  Then select My Queued Jobs.

The errors returned from the queue are as follows:

 Error ID: 24023

 Error ID: 26000

Detailed error below - send it to the administrator for more detailed troubleshooting.

You can do the following:

1. Try troubleshooting using the error IDs, error XML.

2. Contact administrator with your jobID (b5a00d49-63f4-4b4b-aef3-898a522942cf) and error XML.

I went into the ULS logs and this is what I find;

PWA:http://apollo/PWA, ServiceApp:Project Server Service Application, User:SUN\forresto, PSI: [RDS] Start processing RDS job b5a00d49-63f4-4b4b-aef3-898a522942cf. Message type ReportRefreshMessage. Message: RDB area: Epm, error mode: ContinueOnErrors, lock RDB on errors: False, refresh sleep time: 00:05:00.

I'm not sure what all this means so could use some help.  My OLAP cube is not updating properly and I suspect this is a result from the failed ReportingRefresh failed job.

Thanks Forrest
