I cant open maplestory. it says we are unable to connect to the login server due to a server check, a firewall block or other network issues.
Try these steps: Step 1. Right click on Maple > Properties > Compatibilities > Change Compatibility to one (except the first and last, I think) > Save and try to open > If still doesn't open, right click and run as administrator > If it still doesn't open, then repeat from Step 1. and chose another compatibility that you haven't tried yet. If it still doesn't work, then even I'm not sure
