subcribed this file from your website .AEP project file giving error "this project must be converted from version 10.0 (windows64).The original file will be unchanged.

click OK, my friend! :wink:

UPD: It’s not a error. Just message telling you that AEP file was created in previous version of After Effects, and it will be converted to your current version.

Unable to open video open file .Error “After Effects error :file"” cannot be imported-this ‘.mov’ file is damaged and unsupported. my AE version is CC.Please help I’m in hurry.

Don’t open AEP file in zip folder. First extract all files.
Also make sure that you have installed QuickTime player.

Thanks it is working fine after installing QuickTime Player.
