Hello,
1) At this moment I see that both your codes are supported. You should be able to create a new topic. Try and let me know if you still have a problem.
2) If you can’t renew the support for the expired one on ThemeForest contact Envato support. They will be able to solve the problem I think.
3) You can try not just to increase the font but also add the shadow property, why not https://www.w3schools.com/cssref/css3_pr_text-shadow.asp
