Gerber Oddysey48 software help

[rixcorner 0]

Just purchased used machine for my wife.  We know NOTHING about plotters, sign making or anything else. This machine came with Omega 2.1.0.  Instruction book says to load on Graphix Advantage.  I don't have "Graphix Advantage".

I read somewhere that Omega 2.5 replaced "Graphix Advantage". Do I need to get this new version of Omega or Graphix Advantage or some other software to be able to cut vinyl with my Gerber Oddysey48?

I don't see the "drivers" for this plotter in my Omega software 2.1.0  Are these drivers in the other software? :-

Thanks in advance....Rick
