Quick Book Exe Unable To Run Due To Error

Hello friends
I am using quick book 2009 for the management of my business accounts. I have in depth working knowledge but not have much technical grip over the quick book. For two days, I am facing problem in using quick book.
During the usage, quick book application suddenly caused an error and got closed. This happens almost 10-15 times daily that makes entering data / making report a real pain for me.
The error appears is like this.

.NET – BroadcastEventWindow.2.0.0.0.33c0d9d.0: qbw32.exe – Application Error
The instruction at “0x568b29f9” reference memory at “0x03ab2140”. The memory could not be “read”
Click on OK to terminate the program
In this error, the memory address is changed on every occurrence.
Kindly help me resolving this issue if any quick book guru / expert is here in this form.
