X5 and RasterlinkPro users?

Anyone out there using X5 and Rasterlink Pro? I seem to be having troubles exporting some files into rasterlink and I can figure out the cause, most of the time it is on larger stuff like 4'x8' but I don't think size is the issue. Some of the things I create just seem to freeze up when I try and export..... and ideas? Perhaps I could send someone one of my files to look at? I have no idea what it is but I really need to figure this out :(
