You'll need to provide somewhat more detail here. What exact steps are you using to perform the conversion?

FontLab 4.5 is not the right product. You must have 4.6.1 or 5.0.4 to succeed.

I started out creating an opentype font and when I tried to convert it, it crashed fontlab 4.5.

I think I need to try converting instructions and curves and maybe also hints, to truetype first, and there's a couple of other ideas I have gotten recently. I will eventually really try to figure it out, and if I figure it out I will post it, but I don't really care anymore if I do create a truetype or not - I think I will just make opentype fonts.

Yeah I plan to upgrade fontlab ASAP.
