Hi there I have been using MBAM on demand for a couple of years and have been very pleased with it. I did a search for this on the forum but nothing seemed relevant in the results. Apologies if I missed it. I update MBAM successfully. But when I try to run it the program often (not always) hangs after 2 seconds (on the timer). I need to terminate it via windows (not responding message) to close it. When I restart the program it then scans successfully. Occasionally it will hang again at 2 seconds and I need to restart it again before it will scan. This has only started happening in the last month or so and I can see no reason for it. I went into my c drive and found a file called mbam-error.txt saying "An error has occurred. Please report this error code to our support team. MBAM_ERROR_NOT_REGISTERED (0, 0)" This is dated 30/4/10. Can anyone help me get my MBAM working again please? Thanks dilips
