Hi,
Well after several hours messing about last night I worked out the 'Tiscali Web Accelerator' was causing the errors and the crashing, so uninstalled that and everything started working fine again. Rang the helpline and they talked me through everything, uninstalled the modem as the ME drivers were installed and not the ones on the disc so reinstalled it with the ones on the disc and all that was then

configured properly.
Then we tried to go to the IP address 80.5.178.26 to register for ntl services but it kept saying 'page cannot be displayed' or a window would pop up saying 'internet explorer could not open the search page' also tried
http://autoreg.autoregister.net but that just said page cannot be displayed.
The woman on the ntl helpline talked me through 'pinging' the IP address 80.5.178.26 and that was all working fine so she said my pc must be blocking secured websites and something about SSL and I'd have to sort it out myself.
So just as I though it was all ok......it's not!!!
I tried messing about with internet explorer options and enabling more or less everything but it still wouldn't work.
What do I do now?????
