Can anyone help me on why Dr.zx (pc version) with dr.zx cable is not working on ZX-3? I have tried it on ZX-1, and it works. But, whenever I try it on ZX-3, it always says "Communication Error..".I have tried three different dr. Zx cables and two different USB drivers (3.1.2009.6 and 2.8.2007.9) on my win7 laptop. Still no luck. Even the technician, where I bought the items from, doesn't seem to know why it is not working despite the item advertised to work with both ZX-1 and ZX-3. I would hugely appreciate any form of help. Thank you.
