I'm having the same problem. I didn't get a new computer or anything it was working fine yesterday and today it says the failed to find gr2d
I checked the DirectX thing and ran the tests and they all came back positive.
Though on one of the notes it said
" 1)The system is using generic video driver. Please install video driver provided by the hardware manufacturer
2) Direct draw test results: All tests were successful
3) Direct3D functionality not available. You should verify that the driver is a final version from the hardware manufacturer
"
I can tell I have to download something
but I don't know how and where to..

It says my system manufacturer is Shuttle Inc

I don't really know what that is.

Help? I really want my maplestory to work
