That definitely won't work. Sorry.
It is only possible to open some PrE Projects into the right version of PrPro, but will not work the other way around. The error message that you will get is "This Project was created in Adobe PrPro and you need to open it in that program."
Even going the PrE to PrPro route is filled with potholes. I can open some PrE 4 Projects in PrPro 2.0, but not all - depends on what was done. Later versions of PrE will not open in PrPro 2.0, but some have opened in CS3 and CS4, though much can keep one from being able to do that.
Sorry for the bad news,
Thanks Bill, thanks Steve!
I'm cleared. Thanks a lot!
