I'm having exactly the same problem m8 you'll be lucky to get an answer here AA are avoiding this issue at the moment i guess they are trying to figure out how to solve the problem without wasting money....
what they seem to forget is we have wasted £400 of our money buying something that does'nt work and are wasting more money by not being able to do gigs , i'm so fed up with waiting for a solution that i think i'm just gonna try and get my money back now.Its a real shame because i really do like it but it just does'nt work as it should.
