I purchased Strong Bad's Cool Game For Attractive People several years ago. I went to boot it up for old times to do a play through. When I opened it it said that had not purchased the software and needed to purchase it again. Is this a normal thing or did spend the money in vain the first time. I did repurchase it, but would like to know if this is a thing that I need to worry about with the other games that I purchased from TellTale?
