everytime I use the massive synth in a project it corrupts the project so it crashes and that project crashes everytime I try to open it again. Its a pain cos it means I have to stay away from the native instruments synths that I have in case the same happens. Although it doesn't happen with the absynth or FM7. Least I don't think it does. Does anyone know what is wrong with my system? Is it a bug? Is it some kind of conflict? I beg a tech head resolve my problem......My system is a 2008 black macbook with OS X 10.5.8 running logic pro 8. I have lots of plugins installed including IK multimedia ones and some demos. The poll was an accident. Once you tick the box you cant go back!
