I've been having a few problems running Mainstage 2 and resolume avenue off my macbook pro during live performances. Suddenly for no apparent reason all the 8 channels of audio playback coming out of mainstage and all the visuals running off resolume will stop . (quite embarrasing during a gig!)

I thought at first it was the mac overheating but i've realised it is not that now, I'm thinking it would just be an easier and safer soloution to run resolume off a separate laptop .
I only have 1 macbook pro so I'm gonna have to buy resolume again for pc and run it off the windows laptop its not a great laptop! Windows vista, Intel (R) pentium(R)Dual CPU T2330 @1.60 GHz Ram 1789 MB 32 bit
Does anyone know whether I can connect a mac to a windows laptop via ethernet cable and trigger it that way, will they talk to each other? what version of Resolume avenue will i need for this old Laptop?
I'm only triggering one ( 4 minute) video clip at a time, (DVX) nothing complicated no effects or anything.
Any help would be hugely appreciated
Thanks
Nathan
