CONSISTENT PUNKBUSTER FIX
1- go to your "add or remove programs" and uninstall Punkbuster

2- Go to your system32 and syswow64 folder and delete your remaining PB files (should be PnkBsterB.exe, PnkBsterB.xtr, PnkBsterA.exe, pbservice) Delete ALL pknbster files.
(make sure no instances of punkbuster are running in your task manager)

3- Navigate to C:\Users\yourusername\AppData\Roaming\25Assist and delete the punkbuster exe in there (should be pbservice.exe or something like that)

4- restart your computer

5- launch 25assist and DO NOT USE THE FIX PB OPTION

6- join the server you want that has PB the server will install PB for you into the appropriate folder.
(DO NOT MOVE THE PB FILES INTO YOUR SYSTEM32 FOLDER MANUALLY)

this has worked for me consistently, I learned that any other games that install PB tend to break AAO25
If you launch or install another game that also installs or updates PB there is a high likelihood that it will break your AAO25 PB again. Simply repeat the steps above.
(if for some reason you cant find a server that will install PB, try the LGC servers)
This has worked consistently for me 3 times after I had installed other games with PB that updated/broke AAO25's pb
