Version 15 too slow--I reinstalled Version 14.5.1 But it opens as Virgin copy

[TakeTheTour]

How do I associated a reinstalled copy   (14.5.1) so it has all my files, presets, settings etc.???

I did click on a Catalog when prompted but it said this catalog was too new for a previous version.

Version 15 was taking 15-20 seconds for a Brush to open which I use constantly by hitting "K".

This is killing me!!

Hi @TakeTheTour, welcome to the community!
Just a heads-up that it’s not possible to roll back a catalog to a previous version of Lightroom Classic. If you have a backup of your main catalog that hasn't been upgraded yet, you can try opening that in 14.5.1. If you're looking to improve performance in Lightroom Classic 15.0, this guide might help:

Your un-upgraded LrC 14.5.1 catalog is automatically stored in a zip the folder called Old Lightroom Catalogs. This folder is a subfolder of the location where you keep your catalog.

So, just unzip the old catalog and double-click on the unzipped file to open it in LrC 14.5.1.
