SIR

1 simple way you could add a text box which is invisble to the user with some code on it that counts the number of times it has been opened if it reaches a certain number than it runs an uninstall program or just displays an ordering form on load!
I.e
Has invisble text box or maybe just a string!
Onload of form it adds 1 to the string.
When it reaches say 30 everytime from then all froms are hidden except the registration one!
hope it helps
Sir, obviously you'd have to save this information somewhere. And encrypted so no naughty people could change it.
