are you using the full or trial version of windowblinds?. it will make a difference. If you have been using the trial then after the 30 days it will no longer work regardless if you uninstall and then reinstall the program. please copy and paste your windowblinds info here so people who are more knowledgable than myself can take a look. to access the windowblinds info, Open windowblinds and then click the about windowblinds button and then click copy to clipboard, then paste from clipboard into here. You may find if you are using the trial version that your only recourse is to purchase the program, which is not that expensive and well worth the money. But it could be something else. Good luck

This is a problem right here, try rebooting and if that does not work then uninstall windowblinds again and use your favourite registry cleaner to remove all traces of the program from your system. Once that is done reboot again and then re install windowblinds and see if that works. If that fails send an email to [email protected] adding the same info into the email and they should be able to help you out. Good luck mate

Your Windowblinds info should look something like this.....

Some of the dates on your files look old and that could mean a borked install so removing all traces of windowblinds from your system and doing a completely fresh install will hopefully fix your problem. I hope you get it worked out

I did roboot the PC and it works until I turn off my PC to give it some rest and when I turn my PC back on I get this again

I restart the PC and its working again what is up?I have more than enought memory on the HD !?Maybe I need to go back to the older version of WindowBlinds?!

Rebooting will not fix this issue, you need to do a fresh install

Uninstall windowblinds completely from your computer, then use a registry tool to remove all traces of the program from your system. reboot and then do a complete fresh install of windowblinds again. Hopefully that will solve your issue. If not send an email to [email protected] outlining you problem and they should be able to offer further help. I hope you get this sorted mate
