Hi,

ntdll.dll is a component of a Windows operating system which is causing MSN to malfunction. Although MSN is the one crashing, the main cause would be a faulty ntdll.dll component since MSN borrows Windows components for it to function.

To fix the issue, you can try to create a new Windows Profile:

1. Click Start
2. Go to the Control Panel
3. Click on User Accounts (You might see User accounts and family safety, just click it to get to User Accounts)
4. Click on Manage another Account
5. Click on Create a new Account
6. Under Account Name, place MSNtest
7. Select Administrator
8. Click Create Account
9. Restart PC
10. Sign-in to the test profile
11. Set-up MSN

Let us know of the results.

Thanks,

Paolo M.
