Did you use SVPMgr.exe from archive?

Yes, I did. When I used it the EInvalidOp error message didn't show up anymore.

Hi, sorry for the late reply.
After I tried a few times, I found that after I rebooted my computer and install the Lite package,
with the "Reset to default" checked, SVP didn't crash at start up anymore and worked with some files.

It seemed like I had to reset the user setting, which I ain't used to do, because each time I call a reset,
I have to remove the other 3 profiles and have only 1 left, and edit it to fit my crappy computer.
Perhaps I should try to use the profile selection again....

My question: is the SVP user profile forward-compatible?

Oh the other hand, version 3.1.4 doesn't play Real Video (.rmvb) files.... it doesn't smooth
the Real Video formats, which 3.1.3 does in the same computer. Is the support to the ancient format
dropped?

Another issue is the OSD, it seems to be gone. When I play the file at a different time it normally
display the status in green fonts, but it's now completely gone....

Again, thank you for your kind response!

I copied the Dxdiag output below and hope it's of some uses.

BTW the card is Zotac GT520 (brand), the Nvidia driver is 285.79. I guessed maybe it might be
the problem of the Nvidia driver, but the thing is it's not really that broken (SVP 3.1.3 still works.)

Thank you

Exception EInvalidOp in module nvcuda.dll at 0037197C. Invalid floating point operation.

I have no problem in version 3.1.3, but when I upgraded to 3.1.4, I couldn't launch the SVP Manager
with the above error message.
