FileMaker 16 won't launch in Windows 10 with SuperContainer

[lauren@paradisepartners]

Hello,

Since upgrading one of my clients to FileMaker 16 (on Windows 10) and SuperContainer 2.9504, they've been having this problem where FileMaker sometimes won't launch if the SuperContainer Companion Plug-in is in the Extensions folder. In Task Manager, FileMaker appears as a background process, but never finishes opening. 

Removing the plug-in, launching FileMaker, quitting FileMaker, then putting the plug-in back fixes the problem--for a while.

SuperContainer Companion is the only plug-in that they use. 

I've seen this problem mentioned in the FileMaker forums, but here it seems to be caused by the plug-in. Any ideas how to solve this?

Thanks.
