Hi Voorhees, thanks for the reply!
I Input the advert details, select days/price/picture
Click to submit and it crashes mid way through posting? If I then highlight the web address that it's trying to re-direct to and press enter, it says "Thank you for your request, processing (a bit like the login screen/page)" then says I do not have access to whatever hyperlink page it is? :S
I'm on Windows Vista and didn't used to have any trouble?
