Jolly,
I had the same issue with this, I also have an acer with a GT540m and Intel HD video card. snafu777 was able to help me out with this problem. If you are using the 32 bit BT5 you are going to want to use the 32 bit drivers. You can find the solution here. All credit for the fix goes to snafu777.
