Phone Help [Computer Not Detecting]

[Magic]

My computer wont detect my phone for some reason, any ideas why?

[pinkmichk]

my laptop did that with my new phone never did get it working sorry not much help really

Aww dont worry, ill keep trying.

Do you have vista? If it's a slightly old phone it might be because you don't have the right drivers for it that are compatible with vista.
Has it worked before in the past?

[Magic]

Yeah, its worked loadss before. And I am on XP Lauren.
Its so annoying!
