Hatsune Miku: Project Diva Extend

[Alucardx60]

Hate to add to the swarm of questions but I can't seem to get the patch working either. It's probably something stupid. I extract the EBOOT.bin and the Diva2ExData.cpk with 7-zip, patched it, but when I add the files back in with CDmage or UMDgen PPSSPP says "Error loading file: failed to load executable: file corrupt."

I did try extracting EBOOT and Diva2ExData as was mentioned in both LunaMoo and Ritori's tutorials just in case but the problem is probably with how I rebuild the ISO. I use UMDgen since I don't know how to convert .cues. I right click>Add>existing files then add in the proper files and save as uncompressed iso in a different directory but with the same filename.

I'm running the latest stable version for Windows 64-bit.
