No, that's the right version.
Just to clarify.
There is Dragon 1.03.62 and there's Dragon 1.05
My mod (version 9.1, as it's up to) uses Dragon 1.03.62
There is a "test" maptrans file for Dragon 1.05 included, but I don't really keep it up to date, and I don't recommend using it. (It's maptrans105.txt).
If you want to try out Dragon 1.05, then you'll need to rename the maptrans105.txt to maptrans.txt and move the original maptrans.txt (for 1.03.62) someplace else. The format of the file is slightly different so you can't mix and match them.
As for your actual problem with Dragon crashing, I'm not quite sure what would be the cause of it. I'm not much help in this case.
Just to check though, make sure the map0.mul is not read-only? (Right-click it and select properties; there should NOT be a check in the read-only block)
