Software Upgrade for Proceed AVP-S?

Hi All,

Does anyone have the software upgrades for the Proceed AVP-S? I understand there's a cable involved, too. I'd be happy to pay shipping both ways or even buy the upgrade outright. I'm not sure which version software I'm running, but I know that I can't run multiple subs, which is primarily what I'm interested in the software upgrade for.

Thanks,

Jason
