Hi Moritz, the white toolbar problem looks like it's because you're running MoI v2.52 there and not MoI v3. The CustomUI that you've installed there requires new functions that are in V3, the error is saying that it can't find a function because it did not exist yet in v2.52 .

Please make sure you are getting the latest v3.1 version, you can download it by putting in your license key here: http://moi3d.com/reinstall.htm , that might help with your startup issue as well.

Let me know if you're still seeing the startup problem with v3.1 .

Hi Michael,
you're right - I was using the version V 2.5 - for whatever reason - grumble!!!

Now it works great with MOI V3.1

Thank you so much
