I don't get to play games often, and I sat on Tomb Raider 1 for a very long time. When I finally went to play it in recent weeks, I downloaded Glidos, VDOS and all of that.

I unlocked Glidos, buw, t when I went back to play a few days later, it was locked again. I unlocked it again, but, later that day, it locked again to the point where I had to buy the service again.

As I went to use my new unlock code today, I noticed that the Glidos ID has changed, so I assume this is the problem.

Why does this keep happening? Please advise.

Thanks.
