Don, think it's time to bury the hatchett, I did not get angry because of the money, but because anything I buy that won't work at all makes me feel that way...
On the other hand you're obviously moving into the right direction, since your latest software does work on the CIR, OK imperfect for ccf files but at least for me the package isn't d.o.a. as it used to be...
Your credit offer is generous indeed, but I won't go for it- I'll rather stick it out till it really works as I hope it can...
Anyway, I wonder if anybody has a circuit of the 3900 series so we can check why it's not working with the audio plugin?
