Issue with FSINN - FSX no response

Hi all, 

for some a reason I have an issue with FSINN for some weeks. This error does not occur on each flight, but would assume 60 per cent of them. This is very annoying. What happens? I prepare my flight or start FSINN immediately, when FSX has loaded. After I clicked to "Inn Control Panel" to start the client, FSX freeze. In the FSX tiltle menu appears: "no response" and it literally does not respone. I have to restart FSX and try it again. If I am lucky it will work. If not I have to restart FSX until it works.

This is really frustrating. I firstly thought it occurs due to my old FSUIPC version, but I updated it and it did not change anything. What can I do to enjoy FSINN again?
