It's good to hear you can get the software up and running. Are you absolutely sure the reset preferences step is required each time? My hope is that you can get to the welcome screen without having to do that and without the program crashing.
For the auto-save thing, It may well be caused by multiple preference resets, followed by Pr establishing a new auto-save location by the default location, which is next to the project file. Feel free to move and otherwise rearrange or delete the auto-save projects and folders until you make it look like you want it to.
If you do have to reset preferences each time, and that is what is causing the deeply nested auto-save projects, then you may want to establish a permanent, fixed location for auto-saves.
You should also get your prefs set exactly the way you want and then save that configuration to the cloud. It will make resetting to your custom preference set easier.
