One Problem here... Tic Tac Toe by its nature can be tied everytime no matter what if every move gets seen. The checks you have coded in mean that the computer is always going to see the blocks. However the human mind does not run if-else checks quite so flawlessly. Without some random chance of failure in the check the computer is gonna beat(or at least tie) you every time. No matter what.

There should be something telling you which line the error is on. That would help narrow it down. That's a LOT of code to try and digest.
