Your question isn't really clear.
However, I THINK you are saying that Movie Maker closed and asked if you wanted to send an error report.
You clicked OK to send an error report and you are now awaiting a reply to that error report.
If you continue waiting for a reply, you will wait until the proverbial cows come home.
You have sent an error report to Microsoft and, as far as you are concerned, that's it. End of story - nothing more will happen.
The error report goes to Microsoft to let them know why one of their applications stopped working/responding.
They will now use that information to, hopefully, improve that product in the future.
