unlimited license can work in 6.1.4 or not

Can someone tell me whether this unlimited license can work in 6.1.4 v or not - without upgrading the site to 6.1.5 and 6.1.6.

I want to use all ray widgets without ads/links.

-------------------------

I do not want to upgrade now becoz I have some mods installed ( 7 colour template, inviter, google search and adsense). And I read somewhere that when site upgraded then these mods may not work.

Yes, the unlimited license should work with 6.14

There have been problems with the ads reappearing in 6.14 however. Just so you know.
