Whatever it is, I think I've got it too -
first time attempting to play in months, and I get this:

"C:\Program Files (x86)\SEGA\PHANTASYSTARONLINE2\pso2_bin\pso2launch er.exe is not a valid Win32 application"

Da heck?

Does anyone have an idea?

[Clunker]

Thanks for the suggestion.

I've tried that, and the initial option to run the file check will actually come up now -
but it stops checking files at file 9966, and will not go past it.
