Bit more info needed first of all...!!
Can you give us your full system specs...??
You may want to make a signature and add it to your profile, it saves a lot of time and people can see exactly the specs of the PC that they are trying to help with..!!
It needn't be a picture like mine a simple text signature with all the relevant information is fine.
That being said...!!
How many HDD's have you got installed..??
Have you got a RAID array setup...???
When your trying to backup what HDD's are you trying to backup and to where, and how...i.e. C: Drive from HDD 1 (RAID-0 2 hdd's) to networked PC via LAN/WAN etc.
Form the messages you mention it seems that Ghost is thinking your trying to backup over a wireless network hence it asking for the WAN driver, and seems to be having problems in finding your drives as its in a RAID array..!!
I have used Acronis before without any problems to do a network backup of my RAID array on a Phenom 9950 and Vista Home Premium 64-bit.. PC...!!
Can you describe the steps you take when trying to use Acronis...??
