Hi, I have Windows XP Media Center Edition and i installed directx 9 and then P3D editor. But it still gives an error when loading 3d Objects:
SlimDX.Direct3D9.Direct3D9Exception: D3DERR_INVALIDCALL: Invalid call (-2005530516)

I have tried to install many othyer versions such s slimdx, direct3d sdk... but no one worked. The error still appears. How to solve it? Is it an incompatiblity with my OS or with my PC?

PS:i have a old pc from early 2000s.

We investigated the issue, this should work on Windows XP as we just tested it. It seems to be an issue with your actual hardware, which may be why we can't replicate the issue.

You can try to use Lucas' P3D Editor (3.1.5).

Can you send me your system specs (CPU, GPU, RAM, ect)

Ok, old version of P3D editor works, but i can't do not half of what i did with the new version.

Device Specs:

Processor: Intel Pentium 4 (2 CPUs : 3.00 GHz, 2.99 GHz)
RAM: 2038 MB
