Not sure whats causing this, but lop~ and hip~ are sometimes generating the 'PD caused an exception 10H in module PD.DLL'. error, just like the other day with the FFT's. It must just be some objects causing PD to bomb whilst Gem is loaded. I don't think that the FFT objects themselves are to blame, cause some of the FFT test patches work fine. PVOC and similar wont function however. Crash occurs when DSP is switched on.
