I have tried multiple times and on every update since 4.1, including using the multi-version step up method. The file exports just fine, but the import fails every single time on every version. I really don't want to have to rebuild the entire show. My largest rig is over 300 fixtures and 10k+ cues. I am at a loss and not really sure what is going wrong. I really don't want to lose all of the work I have done over the past several years because of a glitch or process I can't figure out. For now, my show will live on in 3.21. I have 13 consoles across 8 campuses with different rigs and shows. So far the 4.x family of software has not been the easiest transition. I get encouraged with each update only for it to completely fail every time. If I can get the biggest show to transfer, then I can begin rolling out to the other 12. I am not sure how to make it work. Please help or just let me know that it's not going to work. I also work as a sub-contractor for a couple of integrators and it is difficult for me to encourage them to use the latest software if I can't get it to work in my regular LD position.
