What you have to know about raw files compatibility:

The main thing to know is that each new camera comes with its own unique raw format. CR2 or CR3 are raw format families, but the converter you need is linked with your camera model.

First find the ACR plugin version needed for your camera, then check if your PSE version can support or be updated to that version. Only the current version can be updated for new cameras.

On the other hand, to upgrade to a newer Elements version, you only get a price rebate (about 20%) for having an older Elements versions. There are generally better prices from big resellers online. Also beware that if history repeats itself, a new version of Elements is expected in the next weeks.

So, the best you can do if you don't want to upgrade is to download and install the free Adobe DNGconverter mentionned in the above faq. That standalone software can batch convert a whole folder of your raw files to the DNG raw format that your PSE14 can read and edit. An additional batch step, but free and with the same quality.
