Ok, I had a post for my video camera and this is the response... Maybe it will help you? It didn't help me at all but I'm not able to get my software on the laptop to stay, but if you are and it's not running this might help you?
Hi cyndi007,

If the above method didn't help you in resolving your issue then, this may be because of some software conflicts. Try performing clean boot on your computer.
Method 2: Starting your computer by using a minimal set of drivers and startup programs so that you can determine whether a background program is interfering with your game or program. This kind of startup is known as a "Clean boot."
To perform a clean boot on a computer, follow these steps.
1. Click Start, type msconfig in the Start Search box, and then press ENTER.
If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.
2. On the General tab, click Selective Startup.
3. Under Selective Startup, click to clear the Load Startup Items check box.
4. Click the Services tab, click to select the Hide All Microsoft Services check box, and then click Disable All.
5. Click OK.
6. When you are prompted, click Restart.
7. After the computer starts, check whether the problem is resolved.
Please monitor the system in the Clean Boot environment. If the problem does not occur, it indicates that the problem is related to one application or service we have disabled. You may use the MSCONFIG tool again to re-enable the disabled item one by
one to find out the culprit.
If your issue is resolved, follow the How to Determine What is Causing the Problem section in the KB article to narrow down the exact source.

Hope this information is helpful.
Let me know if this worked.
