Reloaded LR 6 and file format now not supported
Had to do a factory reset on PC due to other problems.
Reloaded LR 6 ex disc. LR seemed to pick up the existing catalogue automatically with no problem. Older photos seem to be OK (Nikon D5000) but photos taken on Nikon D7500 now give error message "file format not supported", when loaded into Develop module. They can be viewed in Library mode These were previously edited in LR with no problem.
Any suggestions on how to resolve this problem. These are NEF files
Thanks
Mike
