Bhavbhuti:

Can you copy and paste the error message? I have the same problem in the pass using xceed zip activex control. But the problem was that my activex control lost the register and need to be register again in order to be available in the class. I you save the class probably you loose the method asigned to that activex control but if you did not save it and open the class as a database you can check if your method are in the class. Also in a database mode you can see where the activex control was saved originally.
