Safe Zone Browser gives error message and crashes (windows 7 )

Hi Everyone, I have recently purchased the paid Avast after a lot of trouble free years using Avast free, it seems to work fine and I am impressed with the added features in the paid version, one reason I bought the product was online banking and purchasing off the internet, I decided to use the Safe Zone Browser which worked fine once on my bank but after first use it crashes and give me the following error code

The Exception Breakpoint, A Breakpoint has been reached (0x8000003) 0x6434c1d0

I am using it on a desktop with windows 7 installed, I have updated the Programme but still it crashes, does the forum think if I completely unnistall Avast and re install would it cure the problem, I assume the licence will still work.
I have also got a laptop using windows 8 which Safe Zone seems to work fine, can anyone suggest a solution.

If you type breakpoint in search on the top right hand corner of this page there are several answers.

Thanks for the info Marc, I did find the solution a little difficult to find on purely Breakpoint, obviously others have found the same problem with windows 7, I tried the repair option in add and Remove Programmes in Control Panel as suggested and to no avail then I read the post on going into settings on the Safe Zone page itself and re-setting Safe Zone, it works a treat, I would recommend this option.
Thanks
