Unable to import presets to LR Classic 9.1
I bought a new laptop today, as the screen on my old one simply had too many dead pixels to be useable. I have managed to download LR Classic and Photoshop successfully, move my LR catalog across to the new machine, and all is well with the images and being able to select, develop and export them. However I have , despite following all advice, not been able to move my presets across. Please see belkow for snapshot of my system. 
So far I have tried copying the old lrtemplate extension files to the correct "user" folder within develop presets, both manually and by using the import button on the sidebar. I have also been unable to import newer XPM files using the same methods in the appropriate, different, presets folder. I currently have all my old presets which worked successfully on my old laptop, saved in a folder on my desktop as I am fed up with trying to copy and paste them across using a USB. LR classic was up to date and worked perfectly on my old laptop, but I cannot get these presets to show up on the presets panel on the left, no matter how I try to import them. I have followed all available advice on Adobe website, as well as numerous other online forums and advice, none of which have made any difference. I am probably doing something very basic very wrong, but I am stuck and would appreciate any guidance. (All these presets are purchased/free downloads and all worked yesterday on my old machine). Thank you.
