@Boyosolo I may have fixed it in the next update. I think it might be where I'm storing the app data, as it is read-only in some cases. I've changed the location to a more suitable one. Hopefully that fixes it. I'm currently testing another feature I've added, but 1.4.1 should be released within the next 24 hours.

Try running 1.4.0 as Administrator in the meantime. Might fix it.
