SE02 new sounds doesn't "install"

[mkultra72]

So i bought a sound bank and downloaded a free one to try out some new sounds, but uploading them to its internal drive doesn't work.

I've followed the instructions precisely. I plug it into the PC (Windows 10), it detects the drive. I put the unpacked files in the correct folder (PATCH). They copy there just fine. I remove (safely) the SE02 drive, i turn it off/on. I press 4 (UserBank) - nothing has changed, nothing is added, nothing is overwritten.

I've tried both pressing 2 and 3 at start to get access to its drive, put the files on there, they copy fine, they're all in the PATCH folder on the SE02. I must have tried 20 times now, i did a factory reset too. It's a no go.

Using the editor works great, i can save my patches, use the load from file to put them on there... but the .PRM files, no totally useless, they don't load into its memory whatever i do. They don't overwrite my user patches, and after the factory reset its just the factory sounds in that bank.

Any ideas?
