Hi Dimitry, We have seen various issues with GSI not being backward compatible (in the sense that it works differently than before). I believe we have addressed all of those issues for the upcomming 4.6.1 release. We are still in testing mode for this release and it should be out in a few weeks. In the mean time, please stay with 4.5.0.
