Reply to vci 100 midi data problem

I need some help please....

i've just tried to fix a wobbly platter and now after i've put it back together the right hand platter is not sending midi data (other than data to say the platter is being touched)

So now i cannot move the track forward or backward or pitch bend with it.

Has anybody else had this problem and managed to sort it out? i've had it apart a few times now to look at it and still no joy....

i hope i haven't just broken my vci!!

any help will be greatly appreciated.

thanks.
