Hi OP

We think it may well be a cache problem on your browser, which should be fairly easy to sort from your end.
If you don't know how to clear your cache, you can find instructions on how to do it here: www.wikihow.com/Clear-Your-Browser%27s-Cache
If that doesn't sort the problem out, please don't hesitate to come back to us and we'll have another look into how to solve this.
