Your best opting here to to purchase CS6 and keep going.
Save a backup copy of your PrPro CS6 project, then open it up in any script editor (e.g. in Adobe ExtendScript Toolkit) as XML document and in fourth line replace Version="25" with Version="23".
Although it works, bear in mind: no warranties or any obligations. Everything is at your own peril.
If the script editor doesn't work, and you can install CS5 and the CS6 trial on another computer, try copying and pasting the sequences from the CS6 project to the CS5 project and then move it to your editing computer.
Or if you have a system image from before the CS6 trial download, you can restore it and download the CS6 trial again and do the same.
Thank you very much Fuzzy.
Notepad seemed to do the job fine and the project is now working in PP CS5.
how did you do it?
I did what you're saying, but I get all strange caracters, cannot find the word 'version' and 29 words '25'.
Is there a special way to open the .prproj?
PD: I've opened it in notepad, textedit, word, dreamweaver and extendedscript toolkit, all with the same result.
Since CC .prproj files are no longer plain XML documents, but gzipped XML. Hence, if you want to downconvert PrPro CC project, you have to unzip it first: add .gz file extention to the existing .prproj file and extact the content. Then follow the instructions above.
you are amazing! thank you
