Is there anything in the readme about having the first pack?  Or replacing PBO's?  Since I don't have a computer that runs OFP at the moment, I can't download and test it...

alas, doesn't appear to matter anymore...the usual problem of OFP having no sound has reared its ugly head once more....

its of the addons i have but i have far too many to go through them all and filter the one that causes the issue...always happens after i install Kegetys effects enhancements....get riud of that and the problem remains. also very annoying
