Error launching game

Hi guys.

I've recently joined your nice community, reached lvl 51

I cant seem to launch my game, which was perfectly fine ~3 days ago.
I have downloaded and installed the new client.

This is the error i receive:


I haven't made any change to my pc.
Even though, I've tried disabling windows defender and specifically enabling mapleroyals.exe through windows firewall.

I even went as far as re-installing the whole maplestory client, but to no avail.

Help?

 

This thread can be closed.

For future reference, I hadn't the newest client(despite downloading it). A hash of the current client helped me realize this.

If you have the same problem, try downloading the client using a different system\browser.
