I need to update my version of Whatsapp on my Iphone it expires on Tuesday

Go to App Store. Go to Updates using icon on the bottom. Touch and drag down to update the view. If updates are available, you will see the list that can be updated.

Otherwise, you can also remove Whatsapp and then go to App Store to install. You will get new version.

Above is a youtube video in case it may help you.

Please let us know what sort of device you are using .. iPhone, Android or other type as each has their own appstores to use for easiest installation of apps.
You may end up needing to uninstall the one you have which expired and then get the new or free version from the appstore

If you're using IOS or Windows, it appears to be free. If you're using an android system then it looks to be $0.99/year (usd). Let me know if this helps. If not, please say what type of device you want it on. Thanks.!

Because Whatsapp has updated past the IOS your phone has, it cannot be downloaded to the iPhone 3G. In order to get Whatsapp on your phone you'll need to upgrade it!

it does accept new versions have you tried power switching off your device so that it can refresh before trying to upgrade the whatsap version. andalways try to check for new upgrades before the one you are using expires its easy upgrading at an earlier stage.

please update your software and you will be able to use all new apps. whatsapp dont support software version 4.1 it has to be 4.3 or up.
