I have until recently had lifetime membership. I tried to download a pdf guide and it tried to make me pay again. They insisted they wanted my original sales invoice even though I have an invoice on their site. I fortunately was able to find my bank statement which showed I paid them. They responded by saying that was just for he exam engine. I sent them a screenshot of their site which says it is lifetime membership. I also explained that you cannot get the exam engine without getting the pdf guide. They have not bothered to respond. I am going to take them to the small claims court to get a resolution
