Hi, I have two licences for SAS Professional, initially for the 32 bit version. Having replaced one of the PCs by a Win 7 64 bit, I downloaded and installed SAS 64 bit, entered the licence key, activated the product and all was ok. Now, today, I get a message saying the trial period has expired ! So, I re-enter the licence number and activate the product via internet and get a reply saying thank you, your product has been activated. But I still get the message saying the trial period has expired ! So what to do ?
