I was working on an animation in C2 on one computer at work. a 5 sec scene, i was using particle system, lights, etc..everything set up..i had initially saved the file, then did a 'save as' and resaved the file under a different name then burned it to cd and brought it home to work on. but when i loaded the file at home nothing was the same. it was like it was with the initial save. lights id set and had animated werent showing up. the particle systems showed up under the master objects but not the universal objects. im frustrated beyond belief at this pojnt to think all the work id done is gone. any ideas what i could have done wrong? tia..
