Hope this helps!Try this fix as posted by the creator of PB in [Bot] ProfessionBuddy - A Profession Leveling bot plus more
1. Do the SVN download in the bots folder
2. If you can't see PB in the dropdown list for HB, download Microsoft .NET Framework 4 here: Download: Microsoft .NET Framework 4 (Web Installer) - Microsoft Download Center - Download Details
3. Once installed, open HB again to see if you can see PB in the drop down menu
4. If you still can't see it, try restarting your PC. Should work.
