HI all,
First so u know as u will discover it I'm newbie...
About the target:
It is an investing neural simulation program. There is different sub-version in the same v2.4 depending on the numbers of Neurons allowed by your license (from $70 to $16,200).
About the protection:
The program doesn't use any serial but instead when you register, they send you a key (install prog that install a key).
As the fact that how many $$ you pay gives you more or less functions (functions not paid for are disabled) I tried to enable the disabled menu items.
My appraoch:
I first tried to find out if it was reading the key from the registry by setting some breakpoint but nothing came up. Then I tried to find out where the menu items where disabled (enabled at first then disabled at run-time), I was able to enable one of them but as soon as the function was done and before it gives me the result it seems to check AGAIN and gives me a msgbox saying blahblah blah this function not availlable etc.....
I'd like to be able to crack at the source and find out how to simulate the higher level of the key installed ($16.200
but it seems to do test on it all the way through execution... 
Like I said I'm a newbie, I read MANY tutorial, exemples about reversing but nothing comparable to this kind of protection.
I've been using HVIEW, SI, and W32dsm
ANY IDEAS ? Any input are more than welcome. I can send the (registered but without key version if u wanna look at it (coersum@netcourrier.com)
Thank you

PS: sorry for bad english.. french
