Microsoft Remote Desktop - Remote Resource different behaviour than in full client

I'm using MS Remote Desktop 8.0.13 (Build 25377) on OS X Yosemite 10.10.2. If I execute the application (Password Safe 7) on the full client it works fine, if I start the remote resource I get asked for a license file.

I had this problem on the full client as well, but it was fixed by copying the missing files into my profile. I already removed and added the resource back, to no avail.

I suppose there might be a caching issue, but I found not settings for it in the application.

Stopping the application and deleting the content of: ~/Library/Containers/http://ift.tt/1DYv3Rv and ~/Library/Containers/http://ift.tt/1CAkS3w Application State didn't help.
