See the documentation on machine.config/web.config schema regarding
<system.web><machineKey>.

What you will need for you case is to have fixed values for
validationKey and decryptionKey because the problem you're seeing is
caused by those 2 keys being generated after the application is shutdown
and reloaded (which happens when you modify your Bin directory or
global.asax...).
