Cant load internet explorer?

Hi guys, hopefully you can help

I cant seem to open internet explorer? but i can open the "no add ons" version of internet explorer.

Weird thing is i can sign into msn and use the net... but ye, im confused.

When i click the net i get a message saying

"cannot find "http://(weird symbols) make sure the path or internet address is correct"

Can anyone help please?

Thanks
