I bought Spyshelter Premium some time ago. Today I get two messages from Spyshelter notifying me that I must use a new key, starting with version 5.41. The first messages's key didn't work. Then I received a second message saying that the first message was a mistake & providing a "changed" key. That key also did NOT work! I have sent them a message reporting the problem. They haven't answered my message so I still cannot use the latest version of SS. I absolutely detest this comedy of mistakes piled onto mistakes.
