I have Motif ES8 and Window 8 computer use Digital Performer (MOTU)...(used to have a Mac but now DP is on Windows

A few years ago I add the Mlan16E card to my Motif… My windows computer sees the mlan16e in Device Manager, but it had a the dreaded yellow triangle with the exclamation point meaning its not working right.
I tried to find drivers online… didn’t really see anything.
1. Can someone tell me what i can do to get it working?
2. Anyone know of drivers I need and where to get them?
3. If this doesn’t work, could anyone suggest something similiar that would work with Motif? I would like to record sequences in the motif and then transfer them to individual tracks in Digital Performer automatically to so each track I record on motif shows up on a different track on Dig Perf.... as I understood it, this could do 16, which would be perfect.
"new question"
4. If this doesn't work, can I use my old Mac that had DP 5.3 to record the motif tracks using mlan16e and save it to an external and then transfer it to Dig Perf 8.... so I guess this is a "can you use DP5.3 files with DP8" type of questions
Any help or suggestions are greatly appreciated, thanks! Kevin
