Plugin Help PermissionsEx invalid Plugin.yml

Hey guys! First of all, my English is very bad so, sorry for that!
I have a Spigot 1.8.8 Server and I installed PermmissionsEx(PEX). When I restarted the Server after putting the jar file in the plugin Folder, everything was fine! But when I stopped and started the Server, PEX didn't worked!
Heres my console:

Code:

I tried different versions of PEX. Can somebody help me?
Thanks!

@ItzOlin
There was an error loading the jar. Can you try redownloading the PEX file?

 

@Zombie_Striker
I redownloaded 5 times and 3 different versions. All the same
I found the solution: I had to download the newest PermissionsEx. It said it's only for 1.9 and 1.11 I think, but it works brilliant!
Thanks for your Help!
