greetings...

i have a Quark Xpress 4.0 and the dongle was connected before in Mac G4. Then I buy a Mac G5 but the problem is that I cannot use anymore my Quark Xpress 4.0 because the dongle is not matching in G5. The dongle should be in a USB type.
My question is: Is there any adaptor to be used just to connect the dongle in G5? What am goin' to do? Or i have to buy a new Quark Xpress version 6.0 (but it's so expensive)
