Using ArtRage Viate 7.1.1 on Win10

After creating a new Account for PaintLink and typeing the deatils and Pressing "Connect" into the PaintLink Window in ArtRage it changes to Connecting (Einloggen... in german)
From there its stuck..

Is the feature not fully usefull yet? Anyone else haveing an issue? Would this need an Inbound Port that has to be opend on a Router?
