Problem after update

[socialvent]

Hello,
after installing the last update to V.15.02 from 10.11.2019 (64bit) I can't open my projects anymore.
First I could open and edit my old project (started under Webbuilder 14) without any problems after the installation.
When I wanted to open it again the next day, I got the error message that my project was created in a newer version and therefore I cannot open the site.
However, the installed version is the latest version.

Does anyone have an idea?

Many thanks

Open the site and immediately save it under a new name. Then change something and save it. Close off WWB, reopen it and see if your new project is OK.

Hello, Alan,
Thank you so much for your message. I just tried your tip. Unfortunately the error message appears with the program window, so I don't have the possibility to save the project under a different name.

Supplement:
I just opened another old project. This can be opened without problems. After I have made changes in this project and saved it, I can no longer open it either.
The error message that the project was created with a newer version appears again.

I doubt that this has anything to do with the update.
Usually this indicates that extensions used by the project are missing.
For example, you may have installed the 64bit version but did not install 64bit version of extensions.

If you need more help then please share the project file, so I we can tell you exactly what to do.

Hello and many thanks for the offer. I have now opened the backup file, which worked without any problems. Even after changes and re-saving there were no problems with the "backup file".
With kind regards
