Ok, thanks for the log. It is showing that ASCOM 5 is not being recognized by PHD2 at all.
Unfortunately I don't have a simple solution for you. Since Microsoft stopped supporting XP in 2014, developers (PHD2, ASCOM, and camera driver developers) are not able to run our development tools on XP. That means we have no way to diagnose or fix problems on XP.
My recommendation would be to update to a MS-supported OS version like Windows 7 or Windows 10, then update to the latest ASCOM platform. That way you will be able to use the latest and most stable camera drivers, ASCOM platform, and PHD2 software.
If you prefer not to do that and stick with XP, then you'll be limited to older cameras and older software versions that work on XP. Sadly our hands are tied not being able to work on XP.
