Each camera model’s raws must be supported specifically with a particular version of LR that was released after the camera first became available, so it is important what model camera the raws are from and what version of LR you’re running.
Some of the issue might be a setting in Preferences that says whether or not to treat RAWs+JPGs separately, or if it is unchecked, the JPGs become invisible sidecar files of the raws which you should be able to see in the Metadata panel in Library, so check that setting. I think it is in the File Handling tab.
And presumably you understand that once you’ve imported files, then you cannot import them, again.
So report back what camera model and what version of LR, and also what that RAWs+JPGs setting has been set to.
I'm using Lightroom 5.6 and a Nikon D3000.
Have been using this combination for 6 months
I've checked that my preferences handle RAW and JPEG separately.
Still no joy..
ince yesterday when I try and import Lightroom is not recognising any of the JPEG files, only the the RAW format...which it won't accept.
Please explain further exactly what you see on your computer that translates into "not recognising". if there is an error message, please quote it word-for-word.
This is screen shot of what I see.

This error message means that you do not WRITE permission to the destination folder where the photos are supposed to be copied into. Sometimes, this happens because the destination folder has been changed accidentally, so you must see what destination folder is set in your Import dialog box Destination Panel, and then change the permissions to WRITE permission.
Just as a recommendation so you can resolve problems more quickly in the future and save your time and our time, if there is an error message, you should quote the error message word-for-word in your first post instead of using vague terms such as "not recognising".
