hello i am a newbie here, jz registered and i need help

i know there are some article about my topic in here, i followed all the instruction, but still do not help my problem

i have Acer 5553 laptop with bluetooth 2.0+EDR built in, first time i bought this laptop, they set all everything ok, but after few months later i re-format my laptop and i want my bluetooth back, but my bluetooth devices not detected, what should i do ?

i follow these following instruction:
1. http://jonsguides.nfshost.com/bluetooth/index.html
2. http://support.microsoft.com/kb/883258
3. http://support.microsoft.com/kb/840635

ok this what i jz did based on first article:
1.Uninstall all bluetooth software

2.Disable antiviurs and firewall

3.Install bluetooth Widcomm software (which i download it from http://support.acer-euro.com/drivers/notebook/as_5550.html)

on the half-way installing, an error message pop up said: "Bluetooth device not found, turn on the bluetooth and click Ok to continue or click Cancel to continue without bluetooth devices" (this is not the exact error message what i got, but the main point is that)

done! so anyone what should i do ? on the first article tells about patcher, i don't know what patcher, what do patcher do? but i download a patcher from http://www.dev-hack.com/pafiledb/index.php?act=view&id=3
is that the patcher what they were talking about?

sorry my english is not good
