Install issues...

Hi all,

Befor I buy SH5, I want to try SH4. After installing, and want to start for the first time, there is a moving bar. That first moving bar goes to the end.
OK.
After that, I choose introduction (because I'm new to this). A moving bar starts again to load that part of the game. Half way the moving bar stops and all loading activities stops. I have to push the reset button on the computer to go any further.

Does anyone know what I'm doing wrong or is this a known issue or.....

Thanks in advance,
Easy
