[RENDERING EXCEPTION] after upgrading to 7500/7502

After upgrading to 7500 or 7502 I am getting a [RENDERING EXCEPTION] message as the columns' caption of the asset's additional fields I am displaying on the assets grid.

Please advise what to do. This problem has prevented me from moving to 7.5 version!. I've been waiting for days for a solution or workaround from Support and nothing yet
Anybody else out there there having the same problem?
