MFP elevator door problem

[DnALANGE]

I've had the same problem as you!
In Premonition i could NOT repair it.
Took HOURs and HOURS to try rebuild etc etc.
I've asked Patrik this same question but he didnt repond back on PM.
I have no idea what to do, i think the only thing you can do what worked only 1 time beacuase it's remaking the MSH itself. =
DELETE the MSH and try again, you will see it works.
Hope this could help a little Damascus, too bad i could't find any solution.
