Help please!
Sorry for the long post, thought I had better explain in detail....

In PDVD9 had problems with Inception bluray, it would play in a PS3 but not through PDVD9, other discs were still fine. I reinstalled PDVD9 and then CLHelper started crashing everytime PDVD is run. So I decided to bite the bullet and upgrade to PDVD10. CLHelper still crashed. Now PDVD10 still works, but all blurays give error 800401F9, after doing the well documented and seemingly unsolvable region code entry thing with zero changes available.

So I've since uninstalled PDVD10 and all firewall and antivirus software, cleaned registry of PDVD9 and 10 entries and rebooted. Reinstalled PDVD9U and ran the upgrade again but now I receive an error during installation.

The above is the short version of events, several hours spent repeating steps above, with patch, without patch etc plus a system restore.

PDVD9 now wouldn't install; a file, POWERDVD.msi couldn't be found in the PDVD9 installation directory. Omg. So I undid the restore.

Now PDVD9 installs ok and CLHelper problem has disappeared! Hooray. But.. now I get the POWERDVD.msi file missing error now when I try to run the PDVD9 to 10 upgrade installation file that I just bought.

I've tried redownloading the upgrade file again, same error. SO now I can't upgrade to 10.

This time I took screenshots. Attached pic 1 shows the error, pic 2 shows that the file in question, which supposedly can't be found, actually is present in the required folder... pic 3 shows final error before installation fails.

Irony is of course PDVD9 now runs and plays blurays no problem as long as I don't install the patch.

How can I re-upgrade back to 10? Maybe I have the wrong upgrade file? Its called... PowerDVD10_UltraUpgrade_fromUltra_1830_DVD100611-07.exe

Any help offered is greatly appreciated!
Thanks,
Tim.
