While I don't know what caused Incendia to stop
working, I think I figured out a work-around. I was able to get Incendia to run again if I un-installed it and re-installed it in a never-before-used folder. I had used both c
rogram filesIncendia and c:Incendia on both machines before and re-installing it in either of those locations would not work at all. I got it working again on both my XP P1 desktop and my Vista Ultimate laptop by installing it in c:INCENDIous.
