Cant access race

Message from webpage: you need the latest java, yet when I got to install java it says I have already installed. It worked ok 3 days ago. what changed?

Simon, this can be caused by having more than one version of Java on your machine. If you do have more than one, delete them all & install the latest version & things should work. If that doesn't resolve the issue let me know & we can investigate further

According to the website at java.com:

This is happening in Internet explorer. Chrome works fine.

It has all been working previously. Hang on a moment, It may be since IE upgraded to version 11.
I'll check the dates.

yep, that looks like it.

IE11 installed with updates on 12/12/13,  strange it doesnt appear in he add/remove programs or installed updates. I had to look through system restore files to find it.
Unfortunately it was installed with a fair few other updates and programs including flash and I don't really want to undo toe changes at the moment.

I never thought to try a different browser on race day, I gave up after java kept downloading updates then saying I had already got the latest update routine.
