Not newbie: Samples don't load (weird)

I load a sample, if I assign it to a PAD when I load, it works. If I don't do it, when I search for the sample when making a program, it´s not there, like it ain't loaded. Funniest thing is that if I try to load again, it tells me that the sample is already there and ask me if I want to overwrite. It started to act like this in the middle of a project. WTF...

Only thing I can think is to check the file names. Sometimes weird characters or over-long filenames may cause this type of behavior...

All the files in the HD are already renamed to 16characters length. All samples are 16bit 44.1khz. I´ve also noticed that the sample that I load and assign to the pad is not sounding the same as when I play before open in the file browser, is the same sample but sounds like modified, more middle, less hi end. And there´s no FX running.

I´m suspecting it can be the 128MB expansion I bought from MPCSTUFF.com (about a year ago). If this problem persists I think I´ll buy a original AKAI RAM.
