No import necessary, all rigs already available (SOLVED)

I tried to upload some new rigs and this error message came up. I looked through my profiles and the ones I tried to upload weren't there.

I tried again, and now it came up with "memory stick contains no rigs to import". Emptied the memory stick and copied the rigs on it again. The same thing.

I then formatted the stick and tried again. The same thing.

Did the same procedure three times now with no luck. Ideas?

Tried a fourth time with a new stick, the same thing. First "no import necessary, all rigs already available" then "memory stick contains no rigs to import".

I've checked and double checked and the rigs are not in the Kemper.

The rigs are GO-BLACK WINTER by GOlson and the MAKO-RECTIFIER 50-50 by HELL-G

Edit: I honestly think it's the USB port on mine, it's been giving me grief since day one. It finds the thumb drive like 30% of the time and I need to reinsert the drive.

I was able to import the GO-BLACK WINTER with nothing else on the stick, but the MAKO RECTIFIER 50-50 still won't load.

It could be the files themselves, I tried to open them in the kipr editor and every field shows up empty and uneditable.

FIXED: One of the files was corrupted. Strange that it didn't import the other files though.

Sorry, I don't know, already deleted the corrupt one.
