WindowBlinds cannot save changes

Last week I downloaded the update for the WindowBlinds. I can see that all of my previous existing these was in the list. When I put my system to sleep mode and then wake it up then I found that the skin was back to the Windows default. I am having Windows Vista 32-bit home edition installed on my computer. It is simply "forgetting" Window Blinds. Can you tell me that what is the problem with this and how can it be resolved?

Are you having some antivirus running in your computer? If that is the case then what you can do is, just disable that and then apply the changes to that. Once you are done with that then you can again enable the antivirus. Restart the system and this will make the changes.
