Can't open new report in other projects.

We're using 6.8.2 EPPM.

One of my users created a Global custom cost report in a copy of a cost-loaded schedule. He can open the report in the copy of the schedule where he created it, but he can't open it in any other schedules. He gets the following error message:

He exported the report and sent it to me. When I was importing it, I got the same error. When I clicked OK on the message, I got the following error message.

The reports shows up in the reports, but when I try to open it I get the first error message again as he does, and the report won't open.
