Ecsow Dialer says "The Skype rejected Ecsow to access it..."?
That because Ecsow Dialer is not allowed to access Skype due to a previous wrong answer to the access control question from Skype.
To check and fix this, follow these steps:
1. Open Skype and click on menu "Tools->Options". Click on "Advanced".
2. At the bottom of this page click on "Manage other programs' access to Skype".
3. A window will open. It should show an entry called "EcsowDialer.exe" but also may contain other programs. Click on EcsowDialer.exe and click the "Change" button.
4. You should see the window below. Select the top entry, this will allow EcsowDialer.exe to always to use Skype.
