[Help] GUID

[3xigames]

I have a file that I do NOT want in the public.
I don't want it into the public because I want people to pay for it.

I have a subscriptions thing setup.
It SHOULD (Haven't tested) Upgrade users to premium.
When this happens they are able to see certain downloads.

I want them to be able to see my newest program.. but I need it protected!
I got Win License.. Total bust.. Refunded.
I can't do it manually and create a license for every single user.

So I was looking into a few things and there are other sites like mine that use HWID and GUID locks.

When they upgrade their account to premium they are able to see a downloads link IN THEIR SUBSCRIPTIONS area.. I like that a lot.
When they click Download.. it gets their HWID or GUID and embeds the account and password they use with it.
So say their user name is Joe and their password is 123..
If they log into my program with that user name it will check their computer and make sure they are the right user and didn't get somebody Else's user name and password.

So anyone can have the files on their computer.
But when they log in it needs to make sure its the right person.

I think this requires the following.
SQL
PHP?
C++

I have someone who knows a decent bit of C++ but I'm not sure he can do what I need him to.. I Know I can make a log in on my program, but I need the program to link into my database etc..
Its all so hard for me to get..
If someone can help.. much appreciated..
I have a Ventrilo server if someone is interested in getting on..
I can also give you a phone call.
But this needs to be done in order for all my hard work to turn into cold hard cash.
