Open it in CS6 and work out what 3rd party components are used and where.
Fix that and try again in CCwith a renamed Project
OK, i?ll try that but do you think Audio problem is related to these components?
thanks for help!
Hard to say until you indentify the components.
PPro CC has a different location for plugins than CS6... IIRC.
You could try moving them.
About plug-ins i don't know, i have the same configurations on a PC than a few days ago when was working on CS6,
which was trial version so i can't check what components are supposedly missing... no big worries about that.
And my AUDIO issue is also solved, i think what problem was - video clips where taken on 2 memory cards and numbers of clips where doubled
on CS6 there were no problem but on CC when the project had to be converted to new version, numbers messed up
problem solved with restauration of video
