I've been looking at this and eventually found the dll that was used, it seems (most likely) that C++ was used to create the dll, however looking at it, it also seems that to get this working you need to create a web service? Not just a website but a web service as well.
My knowledge in C++ is non existent so I have been trying with C# but to no avail so far.
So I've "cracked" the dll but I just got to figure out about webservices >.<. All I have done for the dll is created a webhost/name that is equal to 33 because in the dll if you open it with any editor you can find their web address teso-service-api.com or something like that, works out to exactly 33. Hope it helps people, I just can't get it to connect to any form of database UNLESS I need to create some form of "register form" in the webservice first?
