Ok you can try to use the back file which automatically saved. Try this:
- Open the project.ccpn file and navigate > ccpnv3 > ccp > nmr > Nmr
- rename the file.xml to oldfile and remove the extension xml
- duplicate the file .xml.bak
- remove the extension .bak
Make sure the new .xml.bak and xml have the same names.
Try to run again. This should open the project. (without layouts)
