My key for lifetime spyshelter stopped working. I was using it within the license requirements, and it stopped working. The developer appears impossible to contact anymore. Others on this forum never have gotten responses to inquiries. I purchased through Plimus, Plimus was unable to offer a refund due to the time of purchase being so far back. But Plimus attempted to contact the vendor and has been unsuccessful. I contacted Citicards, and they said if I write a letter of dispute to them they will reverse the charge, even if it was 2 years ago because this is a clear case of retail fraud. At this point I am trying to steer clear of the product, and have ceased recommending it, or installing it on PC's I work on. It's a real pity, but I think it is a 1-man operation and he may have given up on the product. If anyone has any better contact information for the developer I'd be curious to hear! But as of right now I cannot recommend this product despite it being quite good.
