Internet doesn't work in Parallels anymore!!

i need some help with this. i installed parallels because i needed windows for my online class. parallels was working perfect. but now it just plain out doesnt work. everything seems to run ok but when i launch internet explorer and it says page cannot be found. when i look at my network properties it says aquiring ip address but it will never connect. when i try to right click my computer to select properties to see if i need to install additional drivers it wont open. what i dont understand is why i just doesnt work. it was working perfect then it just cut out. why? help. i need it for my class. thanks!

It sounds like a M$ issue. I have found this in M$ website. btw. What's your internet setup? Are you connected via a router?

well at home i am through a wireless router. at school i connect through their wifi. i only use wifi with my macbook pro.
