Pierre - I used the FB Powerpak from Ross Lambert as a start and put 
together a simple method that gives the user xxx number of uses (or 
launches). It stores the info in an invisible locked file and it is 
written using the binary stream (i.e. not using PRINT) which makes it 
difficult to read if the file is found. The only real downside is the 
user finds the file, deletes it and gets another xxx uses. I've also 
incorporated a registration scheme that forces them to register when 
the uses are exhausted. If you are interested, I could copy the 
appropriate sections of code and send them to you off-list. Let me 
know.

Best Regards,

Brian
