New Update - Error Message

[Oli5]

I'm having major trouble with the new update on my Z3+. I upgraded to Android 5.02 this morning and my phone keeps coming up with the "Unfortunately Google Play Services has stopped" error message over and over again. Also my 4g has slowed down to a crawl (despite showing 4g next to my signal bar), my signal hasn't been higher than 2 bars all day, where it's normally full and a lot of my apps that use data aren't working at all - 9gag, maps etc.

If anyone could help, I'd be really happy. My phone is almost unusable at the moment.

Thanks in advance

I managed to fix it before reading any of this, but thanks for the help. If anyone is having the same problem,here's what to do:
Settings > Apps > Google Play Services > Uninstall Updates.

Then re-install when it prompts you to!
