AEM Injector Channels - Dead?

I was attempting to set up sequential injection on my car today with the aem box (7m) and found that injector 6 wasn't firing (inj 9 output from the aem). I re-pinned the connector to inj 10, and it worked...intermittently at first, and then not at all. Now I figured this may be a wiring issue, so I switched the pins of inj 8 and 9 at the ecu, and switched phasing appropriately to fire 5 and 6 off inj 9 and 8 respectively. As a result, injector #5 (now firing off inj 9) was no longer firing. It looks to me like this is a problem with the aem, though I was wondering if anybody else had the same issue and discovered the problem.

Otherwise, back to AEM it goes. Fuck.

just a follow up - I spoke with AEM and they indicated that both inj9 and inj10 have to be switched on for one of the channels to work. Also, turning the injectors on or off, you have to fully power down the AEM for those changes to actually occur. I'll be testing this theory shortly.
