If you take extreme measures on taking care of the Miracle Seal it will last a while. The quart I have is 6 months old. Don't leave the lid off any longer than necessary. They actually told me to pour what I need into a small container and put the lid back on. Just keep the lid and top of can real clean. I put some plastic between the lid and can. In the past I had some of it go bad pretty quick. It's too expensive to not take care of.
I have had this happen before. Did you try and restart windows? If it doesnt allow you too you can always hold the power button down and it will shut down the machine, then turn it back on and it should work.
Junk previously owned by a vip only has a "perceived" value to those infatuated with the vip. I am sure that the original poster didn't pay much for the rack mount, he didn't even know what it was, and that is why he came here for us to identify it. It is only valuable to a tiny sect of historians that will pay big just for sentimental dreams. If it was a stratovarius, it would have some value. But famous hunters junk has the same value as my grandpas junk. Guitar companies make artist signature guitars and jack the price up on them, these same guitar's come off the same production line as the retail guitars do. Who buys these overpriced things? Only a few fans. Do you have a sports jersey with your favorite players name and number on it? It's just a shirt made the same way a blank shirt is made. What gives it value? It is a "perceived" value only.
