Hi
Are you on OSX? There is a bug where using command-v to paste in a field not only pastes the string you want, but adds a 'v' to the end of the string.
Testing those strings you posted it loaded for me if I made sure the 'v' was deleted (otherwise it would report the invalid key).
I need to look again at fixing that. If this is not the issue then I'm not sure what is up, I tested on windows as well and that had no problems loading the strip.
cheers,
