Odd Midi Issues

Hi, I ask quite a few questions so sorry in advance :(

I have an edirol um-1 midi interface and can sequence my roland d-550 and my roland sh-201 just fine but when it comes to sequencing my Red Square semi modular, it seems to not recognize my midi device. I can play it fine with a midi keyboard.

www.users.globalnet.co.uk/~concuss/concussor/rs.htm The manual is on there

I was previously able to sequence it on renoise with windows xp, but it doesnt want to sequence on my vista machine. Keep in mind my other synths sequence just fine on my vista machine. Does anyone have an ideas? I’ve been plagued with this problem for awhile and dont want to go so far as to have to buy a hardware sequencer…I love renoise too much. Im practically pulling my hair out trying to figure this thing out. Any help would be greatly appreciated…
