Unity5.1.1 makes problems

Till unity 5.0.4 all works fine for me.

I have used unity5.1.1 with the following result:

  • Asset store downloads don’t works. The download begins with 31% or equal, then no progress.
  • I can’t import sound files into a project. I get everytime an unknown error message. The sound file format makes no difference.

Did you submit bug reports?

How can i do this ?

I have tried unity5.1.1 with Windows XP Prof. SP3 and Window Vista Home Prem. SP2.
All 32bit versions.

In Unity, go to Help > Report a Bug
