I purchased the AeroFly 5 upgrade from AFPD for Mac from Ohio Model Planes. The discs arrived damaged. It appears that they came loose from the DVD container and then got scratched up from rubbing around on the plastic container during transit. My computer cannot read the discs due to the scratches. What is the best way to get the discs replaced? I've sent an email to OMP and tried to call but keep getting a busy signal. I'll keep trying to contact them but figured I'd post here to see if there was a better solution. Thanks.
