Error message when upgrading to 1.5

It's already being discussed in the 1.5.0 thread.
Report it to support and attach your last backup file too.

I just got the same error message, did you get it solved?

Hi, I had errors too.
The reason, I had more them 1500 rigs in the KPA.
I even had probs to make backups.
Then I looked in the KPA Wiki of Gianfranco for the system mode to get rid of the rigs.
Erased them, re set the system and the KPA booted well again.
I took the backup of Maurizio threadID=5442 with all good rigs properly sorted and restored them.
From now on, I currently check how many rigs are on the system.
I do not recommend to try my way. It just worked right for me.
It's at your own risk. Perhaps there are better ways.

The root cause have been too many rigs in the system.

Good luck

Thanks, I heard back from support, I also have a lot of rigs and that's probably the problem, i'll try to get it all fixed today.
Thanks.
