Problem with Tree in commercial version 3.6


My problem is: I have a commercial license, one month ago I downloaded update Suite to version 3.6, but not used it in a project. Today I started use version 3.6, and there were problems - not load XML into Tree, bad format or something else, but in previous version of Suite all was all right. Well, I opened samples in folder with Suite 3.6 and I saw same problem! May be I recieved bad package of Suite 3.6?

Could you create a ticket with this issue and describe all the problems in detail?
What exactly sampe could reproduce the issue?
