Rmx 1000 plugin with Virtual DJ 8.1, ''vst is corrupt please try to reinstall''

Hello

In using the rmx 1000 plugin in Virtual DJ 8.1 (32bit).
All was working perfectly until 3 days ago.
Now it says ''vst is corrupt please try to reinstall''.

I did the recommended re-instalation of the RMX 1000 plugin, remixbox V2.1.0 and firmware V2.11, with sadly the same result.

However now the plugin also keeps losing connection with the hardware unit and stil thinks it's corrupt.

In ableton 9 it functions normaly and i've done no recent update of virtual dj.
I recently bought and installed the the new Replika XT plugin from NI.

The main reason i bought an RMX-1000 was the use as an VST-plugin.
I would really appreciate if you can help me out.
