SynthesiaKontrol.exe closes after connecting

[JGastager]

I want to setup my KK88 Mk2 and did all the necessary steps showen by the instruction, but i cant get it to work.
I installed the LoopBe1 Midi Port and did set it up accordingly in Syntesia.
Can it be that the issue is that the SynthesiaKontrol.exe just closes after connecting to my Keyboard?
The keyboard does the Lightshow on connect and the Terminal says "Connected to KompleteKontrol!" but closes instantly after.
Is this normal?
I'm on Windows 10 and did run the .exe as admin.

Thx for any help.

I now tried release v1.3 and it works fine. No crashing. Seams so be an issue with the new version 1.4.
