HFSS v13 start up problem with ASUS HD7850-DC2-2GD5 graphic card

hi everybody,

I did HFSS simulation well with nVIDIA GT9800 graphic card. Expected that simulation time can be reduced, I've bought ASUS HD7850-DC2-2GD5 one. However, after installing new graphic card, HFSS starts up fail. It stands by splash screen then to be idle. I'm using Window 7 x64.

I tried to test by uninstalling new graphic card driver (keep the hardware only), or using the old graphic card, in both cases HFSS runs well again.

Anybody has met this problem, please share your experience!
and does HFSS v13 support AMD platform?

Thank so much!
