Hi! I own a Pod UX and I've purchased the Metal Pack addon. Today, i've bought a used Pod HD300 and I wondered if the Metal Pack Addon I've purchased earlier could be inserter in my Pod300. I've tried but it doesn't seem to be seeing it in any way. Must I buy it again for my HD300, or is there something to do to make it work? If it can be of any help, on the Line 6 webpage, on the "Autorised" page, my UX is detected, as well as my computer, but the HD300 isn't, even thought i've downloaded EzMonkey (which autorised my HD300 and allowed me the updates). Thanks in advance for your help.
