BSPlayer not playing ASF (WMV/WMA) files

[JaysonG]

It's a common problem from what I see in the search where WMP plays these files but nothing else will. I've done a search and tried everything recommended to no avail. I've tried installing:

WM9Codecs.exe
wmpcdcs8.exe
wmp6cdcs.exe
wmfdist.exe
wmtools.exe
Microsoft MPEG-4 V1/2/3 VKI Codec
Even tried re-installing Direct X

I'm guessing some dll (the one that handles these files) is damaged but a lot of the codecs and apps I've listed above are detecting I already have WMP10 installed and not installing themselves properly (if at all) and of course I can't uninstall Windows Media Player.

I'm at a loss for what to try now so any ideas, advice or tips would be greatly appreciated.

Thanks.
