I reistalled LrC and Ps.. I get the same error/issue whewn using a non afobe product like NEO.. I can get the file out of LRC however cant SAVE it or apply my edits that I did in the other program back to LRC..
I note you are looking in Collections (in the screenclip). It is quite possible that the TIF files are coming back into a FOLDER, but not necessarily in a Collection. Search in Folders (Folder panel) by filename.
I did find the file under Library and in All Photographs.. However I would be editing the file under Develop then "edit in" whether I went to PS or NEO and then back to LR after a save ar an Apply it wogd go in the same collection thatI chose "edit it" .. The way it works now is not right. any setting that you know of for this?
