OMFG, why do i always have issues with ANYTHING stardock related, good god. I finally get it to show the new update in impulse but now i get an error retreiving data and it won't download the new beta. WTF!!!
Take a deep breath. Keep in mind it's a beta. Now, I think if you right click the update for Windowblinds 7 in Impulse, it will give you the option to verify if the download was a success. When I first downloaded it, it didn't take, however when I right clicked and was given the option to verify, it gave me the option to download it properly, and then it took.
Seriously....there really are worse predicaments to be in than a mis-download from Stardock (I'm not always calm...most people here know me to be a foul, bitter, negative individual, so these reassuring words coming from me should tell you, your issues with the download are pretty simply to remedy).
