Cannot open .cx3d files with new Creality Print 4.3.8

I have just upgraded Creality Print to 4.3.8 and now I cannot open ANY of my previously saved .cx3d projects!! Disaster! Please help ASAP as I now cannot open any of my files which I have spent many hours creating. Thanks.

Hello @Dam_Buster :wave:

Welcome to the Creality Forum…! Creality

See if you can find the Creality Print setup file you used before you updated…
On mine the project files are .cxprj

Or go here to download an earlier version…
