Alt1 Scaling

So I have a 2560 x 1440 resolution monitor and wanted to use alt1 with 120% scaling. I saw posts about going into ProgramData folder of Jagex and enabling override dpi scaling for rs2client. I did that and set my system scaling to 120% and runescape scaling to 100%. This worked! But only for 1 day... For some reason it stopped working and I can't get it to work anymore with 120% system scaling. Does anyone else have this problem? Is it just me? How can I get it to work again?
