Hello, and apologies if I'm repeating a common issue.
 
I am attempting to register SONAR LE onto a new computer (Windows 10). I have copied and pasted my registration code as an administrator into Sonar, and I receive the message: "Invalid registration code. Please make sure you enter the product registration code exactly as you received it from Cakewalk." Well I know I'm entering it exactly as it is. I've copied it, tried it without dashes, tried it with lower case instead of caps, etc. but no luck.
 
Any tips? I was using Sonar on a previous computer. Do I need to somehow unregister it for that computer? If so how?
 
Thanks

To be honest, I wouldn't even bother with Sonar LE. You can get a better version (Sonar homestudio) for free.

You need to run Sonar as Administrator to enter the code. 
X1 LE is pretty basic, I have it but no long have even installed it.
 
You can still get Home Studio for free which has a lot more going for it.
