It's a new day in December but I can't open any new presents.

Electric December is unusual in the way it is always changing. If you have this problem, you will need to refresh your browser by pressing F5 [on a Windows PC] or Command-R [on a Mac] while the calendar screen is visible.

If this still doesn't work, you may need to change your Internet Settings and then exit your browser and start again. You should make your browser check to see if pages have changed every time you start a new session. For example: In Internet Explorer, go to Internet Settings and click on 'Settings...' in the Temporary Internet files section of 'General'. Set 'Check for newer versions of stored pages' to 'Every visit to the page' or 'Every time you restart Internet Explorer'.

I can't see anything when I try to open a present box on the card.

Don't forget that the presents can only be opened on or after the numbered day of December. So for example on day eleven, there will be eleven presents that you can open - you'll have to wait for the next ones day-by-day. But you can look at all the cards for a taster of things to come and send them to your friends.

Many of the presents use dynamic extra features that you may not be able to see without downloading some small, additional bits of 'plug-in' software for your browser. You can check that you have these plug-ins by clicking here to go to the Electric December browser plug-ins page.

A present window is open but nothing seems to be happening.

Be patient, some of the presents will take a little while to download. Each card gives an indication of present download times.

Most of the presents rely on you moving your mouse about - roll, click, point, click again and just keep on exploring. Each time you come back to Electric December try the presents boxes again, there may be something you haven't discovered...
