Companion IO: Error in cmdConnect_Click

[maqor]

I installed ED-IBE, started it without problems. Then I opened the comapion menu via "IO"-> "ED Companion".
I entered my credentials, clicked "Connect" and then a window displaying the error popped up.

Restarting the IBE didn't helped.

I've attached the Exception log.
Sadly Github won't allow me to upload the dumpfile because the dmp-format isn't supported.
