i started new animation job , entire studio using flash 6. wanted work done @ home, bought flash cc under assumption use files again @ work. completed scene on weekend, no issues, brought in studio morning , file refuses export swf. attempt test scene, flash freezes ten minutes, , .swf comes lacking tweens , keys, symbols missing colours , parts, , once .swf closed, .fla has of same issues (tweens gone, symbols messed up). before exporting .swf, file looks should. tweens there, symbols fine, thing scrubs perfectly. act of exporting .swf seems causes issue. studio tech guy suggested might have cc's publish settings, i'm looking @ them , they're same (with exception of actionscript 3). i further tested scene in old cs 5.5 flash , worked flawlessly in that. 6 seems having issues. any thoughts? flash 6 old understand current fla file format. did mean flash cs6?
