Can't paste keys from clipboard

[nuXNub]

Greetings,

After registering, I was able to generate license key for Screenshot Captor. Selected the whole key text and copied with Ctrl + C.
I then launched the app and clicked About ( Enter new key) and clicked again until I reached the window requiring me to paste the
license key. Clicking 'Paste from Clipboard' however failed  to paste the key therein - nothing appeared in the window! Ctrl + V too, failed to yield any result. I browsed the forum but was unable to find the solution. How do I resolve this? 

Thanks for your help.

p.s will I lose the license already generated and if I do, can I generate another?

Did you try right click and copy/paste rather than using shortcut keys (Worth a shot)

Don't worry you can always generate another.  Sounds like it didn't copy the first time you tried the Ctrl+C, so just try again.
