At first this product worked great. Then all of a sudden I get an error message "A licensing initialization error has occurred. Please contact customer support for more assistance. Error 0xc004d301" Knowing the extreme difficulty of getting any reasonable support from Microsoft, I uninstalled the program, deleted all findable entries in the registry (Windows7)and reinstalled. I got the same message almost immediately. With extensive research on the error a lot of other people have had the same problem. It seems Microsoft would publish an easy fix as I am sure that would far less time consuming than thousands of people calling their support people and spending numerous hours on the phone. As for other products, I an reluctant to purchase anything from Microsoft. I liked the product but at this time it is useless to me.

Used this for yrs to help with sleep problems. Usually get it somewhere else, but was ordering from Amazon and needed to get my $35 for free shipping. So found they had the Calm, and at a very reasonable price. Taking it right before bed not only helps me sleep better but also keeps me regular. Maybe too much information, but it may help someone. :)
