Photoshop Errors

I use Photoshop daily, it's updated. I added text to an image and when I go to change the font, I highlight it like usual, then go to the font I want and it un-highlights and won't let me change it. I used it yesterday with no problems. I restarted the program, I use the Desktop version, twice and nothing. What should be a 5 minute project, has turned into two hours of frustration. Anyone else experiencing issues like this? I need to get a file out tonight and this just isn't cutting it.
