It's been a while since I purchased a new or upgrade version of Take Command so I would like to know if I can still take advantage of the upgrade pricing with the version I have.

The last purchase I made was for version 13, back in 2011.

Can anyone tell me if I can take advantage of the upgrade pricing or if I have to purchase a new version instead?
