What I discovered on FPS creator

I used this software(the Free version and the X10), and it's very nice. The AI scripts are good, the lights too, the sounds are very realistic and the models too. I've got only one problem: the textures in the test game and the created game are not good arranged(example: an officer has got the head skin on his leg and a soldier has got it's hand skin on the feet).

I looked at my system components but I'm not sure what's the problem. There are them:

1.Windows 7 Ultimate OS 32bit

2.Intel (R) Pentium (R) CPU B950 @ 2.10 Ghz Dual Core Processor

3.Nvidia Geforce GT 540M video card

4.Ram 6.00 GB (2.00)

DirectX 10.0

If you can tell me what's the problem please write me at [mailto:octavian.chiliment@gmail.com octavian.chiliment@gmail.com]. If there is a problem with one of the system components write its number and explain me what you think.
