Question/Help Need: Drum Program Created, Need Help

Guys,

I created a drum program earlier this week. I saved the program file within the same folder of the samples that were used. I didnt change the names of any of the drum samples that were used, but upon loading the drum program the pads are all empty. I went to pad assign to see if the previously assigned drums were still present (they were not), however the software says that the drums are assigned to the pads. One thing thats different though is that there is a question mark in front of all of the names of the drum samples. I.E:

?HiHat8
?Kick8
?Snare8

Anybody know whats going on that could yield some assistance?

Thanks all

Alright, this is really weird and I cant quite figure out whats wrong. I saved the XPM and wave files in the same folder to my desktop and the MPC found and opened that drum program easily with no problems. However, that EXACT same program from the same folder with the same samples couldnt be opened from my external hard drive. The thing that really boggles my mind though is the sampling laid bare materials I have on that same external hard drive, and it opens fine. Wondering if there's some sort of minor bug in the file naming or something.

**EDIT**

I had the folder that contained the kit labeled -My Drums (so it would always appear before the other drum folders). Apparently this is what caused the issue because renaming the folder has the drum program working fine. Not sure if this is a bug or not but I'd like the functionality to be able to use -[Insert Name Here]. Not a big complaint though, i'm fine if they never add it.
