Arrrg. How long has it been broken?

I'm trying to create a sample map of a one-period triangle waveform .wav file all the way from C-2 to G8, but whenever I try to save it after having saved it once already, the entire sample map just gets cleared. When I try to create another processor, the wave on the sample editor doesn't show up. When I try to convert that sample map into a wavetable bank, the wave doesn't show up in the spectrum preview.
