Hi greensock,
thanks for answering, unfortunately it is not so easy to do it for me right now, because the project is very big and we have changed some code too.
I always like the latest versions of every software, but this would be only a step to realize what the problem is about and then we'll fix it to be working with 11.39, that's for sure. And if we see that we have the same problems with 11.12, it's already a big big step.
Please..
