Can't import photos from files and folders

Question

Elemetns 11-- jsut bought it yesterday. Have used previosu versions for years but not on this pc.
Each time I try to import, it goes thorugh some number of photos, up through 2,00 plus sometimes and then says import failed and I get nothing. It claims the file is the wrong type (only jpgs and psds). I don't know what the stumbling block is or why elements doesn't jut ignore files it can't read and go on to the next.
Any help. AT this point Elements is totally useless for me.
tia,

Answer 1

After posting I tried importing one directory at a time until I found one that made elements screw up.
thentry smalll groups of files in that directory until I, like running through a binary tree, narrowed down the offending file.
Then I remoce that one file and continue searching for the next file What should have been a single operation taking minutes was very tedious, manually wading going through hundreds of directories and thousand of files.
Outcome:  there were 3 troublesome files (each in a different directory) holding up the import of more than 11,800 files. Shame Elements couldn't just offer to skip a file it didn't like instead of self-cancelling the whole import operation. cost me many hours of time. I'd call this a critical bug in the program error handling. I am amazed that a program this old, that's gone through as many revisions as the elements organizer has a bug in th error handling like this.
