Can somebody please help.

I downloaded the Video-SL 1.1 and I was asked for my Plug in Code. I typed my plug in code and it does not let me Authorize. I tried lower case lettering and etc. The only way it plays now is through DEMO.

Yes, this is a code I paid for almost 2 yrs ago.

My Videos have been working great for 2 yrs (Non DEMO version) until I upgraded to 1.1.
