Hello!!
I just had this error too yesterday, and spend my time searching the web for a solve of this problem, believe me i tried everything, I visited so much websites and forums, and NOTHING, I was going to explode my pc, but at last i FOUND THE SOLVE!!! I have AVG antivirus, AVG give me a warning and I don´t look it, so I check the VIrus Vault and found the file IMPORTERPROCESSSERVER.EXE there, I just restore it and put in the EXCEPTIONS area too, and VOILA!!! PROBLEM SOLVED!!!
I hope that will serve to everyone!!!
Regards,
Glenn
