Hi! See if any of the items in the solutions thread work for you: https://forum.playphoenix.online/viewtopic.php?f=26&t=5468
That said, you probably need to make sure you are properly installed and patched. If nothing on the solutions thread works for you, you can try running the Live patcher, then run the Phoenix patcher, and then run the phoenixfixer.exe and click the 'downgrade' option.
