Hi Domarin, just added a way to reopen a project which was compromised in some parts. It will load all the data and report the failed items. In your case only the ChemicalShift List was lost, but it can be easily recreated automatically. We are still investigating why this happened in the first place.
Please remove all the extra files in ccpnv3 > ccp > nmr > Nmr and keep only .xml.bak and .xml
Updates available soon.
