Ok, I bought an upgrade for WindowBlind. I installed the Impulse and when I to the download section it says Windowblind 6 which when I go to install says it is not supported by my OS (Windows 7 x64) So I tried to download WindowBlind 7 from Download.com and once I tried to install it, it tells me that I can't because I have MyColors installed. So how do I get a WindowBlind Theme to install with MyColors, or do I just uninstall MyColors and install WindowBlind 7?
