I recently purchased my acer aspire 5552 (6/13/11-Online at Tiger Direct). naturally my warranty has expired and my hard drive went bad last month. I spent $65.00 for a diagnosis to determine what was wrong. I then took my laptop to my local Tiger Direct store (Euless,TX) and they confirmed that the hard drive was defective. I had them replace my hard drive and OS (Win-7) costing another $194.00. The laptop has been running fine since then, however I just recieved a message that all windows options will be terminated in 13 days if I do not provide a Product Key #. I know the Product Key # is posted on the bottom of the laptop, but my concern is, what or who do I contact if that Product Key does not work?
