Derainbow help

I have been trying to get DeRainbow to work and for the life of me I can't figure it out. If I am not getting an msharpen error I get a maskmerge error. Am I missing any .dll's At the bottom is the code I am using for my DeRainbow.avs. I am brain dead. I search for hours last night and all the threads I found did not help. I am sure it's something simple I need to do. Thanks for your time. -TM
