Question: Rm1x & VST sync problems

[cris f]

    Anyone else running the rm1x synced to cubase vst?  I had it synced and
running well the other day, and laid down a new track. However,  i've come
back to the project and mysteriously when i attempt syncing the two (via
midi clock), cubase will start/stop the rm1x, but the bpm is completely out
of whack (the rm1x  plays at about double the cubase bpm). The LED on the
rm1x indicates that its in fact in midi clock mode, but the bpm's will not
match. I haven't changed any of the sync settings in cubase, and have also
tried turning off both systems and starting fresh....to no avail. Anyone
have any ideas??
Thanx,
cris
