Game Froze when moving into the 3 building

In my first game save on a bought copy (BTW) i got to year 31 and i was trying to figure how to move into the bigger space so i hired a employe and it gave me the ability to move into the building, So i did the screen went black sound was playing but it was frozen. tried booting it up again and it worked, thinking i was a weird glitch i tried it again… same thing it froze and i guess it auto saved when moving into the new building and so now i cannot play the game because it will not only freeze my game but make it so i cannot even shut off the program.I would love so help because it is a great game but i cannot play because of the glitch, (BTW) i have installed the new patch and same problem. was hoping i could get some help with this problem.
