No environment visable after upgrading to 2015

[Global-e]

After installing 2015 (inc patch 3) and migrating from 2012 its only possible to see my entirely environment with de built in administrator account. When I logon with my Windows Account Visionapp starts normally but opens with a empty screen (No environment) I readded the windows domain groups to VisionApp and gave theme SQL rights on the new database but still not working. How is is possible to let me see the migrated environment in VisionApp 2015 with Windows domain accounts. In the old 2012 environment it works like a charm.

Kind Regards,

Carlo
