Now come the game with nuBuilder. I was try it on my other computer with both 64bit Windows 7 Ultimate and Windows 8 and had problems with display. May that were because of Google chrome. So I installed Windows 8 as 32bit on an other computer with IE10 because the people from nubuilder told it's a problem of Chrome!!
Have to check that now but today. It's already 22.30 in Thailand and I've to wake up at 6:00 so bedtime is in order right now.
Again, Thanks a lot for your help and hope I don't need to come back with same again!!
