Adobe Illustrator CS5 on Mac OS El Capitan Vers. 10.11.3

Hej guys,

I do have a massive problem,

Everytime I use Illustrator and just Illustrator, Ps and In don't have these issues, the application just crashes. Either it is when I want to save something or change a font, any font. Then I searched the internet for solutions and tried to rename the CS5ServiceManager in the library to CS5ServiceManager.bak. But unfortunately it didn't work as I hoped it would.

Now I cannot see the fonts at all once I go through the Character dialog on the right hand side of the Tool bar.

If I go through the top tool bar I do see the names of the fonts but no preview.

What can I do so Illustrator is secure again?

It happens on 2 seperate comps! so it's on my MacBook Air and my iMac.

Please help me need to design some stuff and it is really hard to do it without this program.

Cheers guys.
