Cubase 8.0.2 unable to open 8.0.1 projects, even templates

Hello,
I just updated to 8.0.2 (from 8.0.1) and it will not open any projects created in 8.0.1, including templates.
Help!

PS. I tried opening up an old project in 7.5, saving it as a 7.5 project, and got the same error message. The message I get is the following:

Project “x” was created with Cubase Version 8.0.10.
This program version cannot load it.


Project “x” was created with Cubase Version 7.5.
This program version cannot load it.

I’m having the same problem, but it’s inconsistent. I have 8.0.20 but am not able to open some 8.0.10 projects.

“Project “x” was created with Cubase Version 8.0.10.
This program version cannot load it.”

There doesn’t seem to be any rhyme or reason to which ones open and which don’t, but repeated attempts to open an un-openable file doesn’t work.

I was able to open a couple random 7.5.20 projects.

ah, just posted the exact same thing in the main forum… damn yes… it drives me nuts…

most projects are opening fine but “some” are not opening - giving me the exact same message…

What to do? I need to open them. But I am since 2 weeks in 8.0.20 and started important mixing sessions here so I do not want to rollback to 8.0.10 … what is causing this? This is a PITA!
