unanswered Can't export ROMs in PPRE 2.2.0

[MackanK]

I've been trying to make a mod of Pokemon Platinum (US) and thought I would use the PPRE 2.2.0 editor to make changes. However, when I try to save the project it only creates .pprj-files, and when I try to choose Export ROM, nothing happens. Creating a patch doesn't work either. So what do I have to do to save it as a new ROM (.nds) file? Thanks for your help.

What kind of changes are you making? If they are script related, I would recommend using SDSME for that.

I haven't made any specific changes yet, but it doesn't matter, since I can't save as a new ROM with or without any changes.
