I am contacting them now. Just one question: I've seen in other threads that they've installed .NET Framework 4.5 and 4.5.2. When I downgrade to 4.5 and install 4.5.2, it updates automatically and 4.5 gets removed, right?

EDIT:
Support said that they can't do anything with it and it's out of their support boundaries. Now I'll just have to wait for someone to come with a working solution.
