So you're trying the File > Export > Video Via Adopbe Media Encoder route?
Does it work if you instead just open up AME and import the .chproj file from there?
Are your file(s) on an external hard drive or cloud-backed folder? If so, does moving them onto the desktop locally help at all?
Hi! Yes it worked! I opened the AME and then it has worked!
Thanks a lot for your help...
one question more: does CA support german language? i think it does not?
Yes it should! I think you can set your language preferences in your general Creative Cloud settings if I remember correctly, and it should pass through to whatever apps your download...
