I'm having issues launching Minecraft. I am given the message "unable to start Minecraft. Please check your configuration" and going through installations > new > versions, there are no drop down options for Minecraft versions. Also, when pressing versions, a message pops up "unable to get details." I already tried uninstalling and installing. The checkboxes in installations are all checked off and it still didn't fix my problem. I've also located my .minecraft folder and there are no files besides "webcache" and logs.
