Just a thought, have you tried doing a factory reset of the board? For the small ASA leak, is it leaking out of the lever? If the marker has been in storage a long time and not fired possibly the ASA/Relay Reg needs a bit of lube. You could try a couple drops of marker oil in the ASA prior to airing up. Be careful not to get any on the tank o-rings though or you will have a tough time unscrewing the tank later. As others have said, a quick email to email@example.com
should get you help from Kee and an RMA if necessary.
