BPM stopped

Hi,

I transfered a composition created on a Arena 4.1.7 on a macbook pro to Arena 4.1.8 on a PC media server running Windows 8.1 and all of a sudden we lost the BPM. The PC server has an OhmRGB MIDI controller connected to it but only a few keys have been programmed and none relate to BPM.  We've tried resyncing the BPM, quitting and restarting Arena 4, rebooting the computer, and unplugging the MIDI controller but nothing will restart the BPM. When I transfer the composition back to the macbook pro, the BPM works fine.  Any thoughts?

Please help. 

I didn't find the right solution from the Internet.
