Several weeks ago I installed another external hard drive on my laptop. Suddenly, as of three days ago I am unable to open this progam. It demands that I activate the hardware, which I have tried to do several times online, via telephone and online customer service. Because this is older software customer service recommended this forum, as they were unable to help.
The activation servers for CS no longer exist, and it's long-past the period when Adobe will provide installation support. Sorry.
