Fix bugs in an existing DLL that retrieves information about a poker site

I have an existing c++ DLL (with source) that injects code to retrieve information from a poker client such as total pot size, actions of players, bet sizes, etc. It communicates the info through named pipes. All the functions work correctly on a No Limit Hold Em table, but there are a couple of bugs on Omaha tables. The site uses LUA scripts, so some knowledge may be necessary.
