This message may appear upon launch of the program due to one of two things; the program may already be running and therefore cannot re-register the hotkey as it is in use, or there is another program which is using this hotkey. Press Alt + S to check if the SpotlightX bar already pops up, or if something else does.
"Couldn't load folder: <folder path>"This message will appear when the program has attempted to find a folder at the given path from a previous addpath command, but has failed. Please check that the path is valid (no typos, strange characters, pointing to a file and not a folder, etc.) and make sure to use the command removepath to remove the incorrect path from the path list.
