error:error retrieving data while re-download windowblind7

Hi all.... my problem solved.
I have done follownig guide within impulse from technical support :
-Click the blue menu button in the upper left
-Choose 'Preferences...'
-Click the 'Reset Data' button
-Close impulse and relaunch it, but I still got error message and not resolve, so I tried uninstalling Impulse, rebooting my PC, and then reinstalling from the latest installer impulse_setup_full.exe 29.6 mb from this link http://www.impulsedriven.com/impulse_setup_full.exe  and worked fine but took longtime and there is no sign that installation will completed so I decide to stop impulse and click prompt button to stop, but when I stop impulse I got message that installation of windowblind 7 completed. This is little bit strength for me but work anyway.
Thank you for stardock technical support assistance and best Regard.
