all current releases and betas
In the context of the OP, my statement is correct.
As for MyColors, or it's themes, as a discontinued program is not a current release. I never bought any of them, and only had the free releases but I can understand your wanting the paid ones to be available for download and to work.
The WB's for some, such as Gloss Grey and Gloss Burgundy were encrypted, which makes them unusable now without MC installed. Some, like Winter, won't even apply with Theme Manager. without being activated by MyColors, a major FAIL, imho. (If TM worked in the first place.)
There were a few I actually liked, but being encrypted also crippled the ability for the community to make matching skins for them.
As you may know, they were for the most part, for XP and not Vista/Win7 ready.
MyColors was a nice idea that has run it's course and like any app made for previous OS's there is no guarantee that they will work in the future on another OS.
Who knows what Windows 8 will break.
