not sure why it would be crashing works fine for me and ive had no other reports of DX8 crashing. do you know what line its crashing on?
EDIT: i have finally been able to replicate but unfortunately do not know why. everything should be the same as far as the provided DLLs and .a files go. i diff'd the source vs 0.14 and didnt see anything obvious that would be the culprit. im looking into alternate methods now.
FYI, i have changed methodologies on the building of the DLL and .a files. there is a new IrrDX_v1_0.zip so please redownload using the link above. you can safely remove the D3DX81ab.dll and D3DX92ab.dll files from your system (unless you have older Irrlicht.dll files running them).
