Problems With Touhou Stuffs

[thriller77]

Okay, i'm actually don't want to create this new thread, but well.

so, i downloaded FDF, both Koumakan and Youyoumu FDF, and both of them can't even start.
When i tried to check my Task Manager, it says that the program runs for a few seconds, then just vanished.

BTW, this problem only occurs when i tried to play the steam release.
When i Played the Developer releases (1.02 and 1.03) it works just fine.

This annoys me, especially since there's no english translations for both games except for steam releases and FDF PCB only released on steam.

Anyone please help!

Update:
No. Actually when i'm using FDF Koumakan ver. 1.02 and 1.03, the FPS are dropping to around 20 to 30s. And when i'm using bombs or fight against Nix, it crashed.
BTW, I'm using Acer Aspire 4755G with Intel Core i5 2340M and NVIDIA GeForce 540M

That's it.
