Default [Q] Fontster messed up my phone?

So I have an att galaxy s4 stock 4.4.2 rooted. I wanted to try something new and downloaded fontster to install some new fonts. When I tried to install some fonts fontster stopped working and crashed. Then I rebooted my phone to see if anything changed then nothing happened. I tried to go on chrome and it keeps making aw snap pages and anything on phone that connects to the internet now just crashes right away. Is there any fix? WHAT DO I DO?
