Right. Try downloading v0.07 - It may have the problem fixed.
If you're interested:
to print out the extensions that are supported, R4 scans the extension string, and replaces space characters with 0 then prints the string, setting them back after. This shouldn't be an issue, except you can bet that some manufacturers put the string in protected memory spaces, which makes windows stop R4 with a memory access error, even though it wasn't doing any harm.
Serves me right for doing such a hacky thing
