Default [Q] Viper 3D 1.6.3 Venom HUB not working

After flasing the Viper3D 1.6.3 ROM (full wipe/format with 4EXT) Venom HUB is installed, but not in the accountlist.
When startup Venom HUB, I have to fill in a username. When I do, venom HUB is still asking for registration.
When I click on one of the venom HUB options, a whit screen appears and keeps white. Nothing else happens.
Also the text in the left top "click here to register" keeps standing in stead of an optional username.
Can someone help me with this issue?
