I press "Start", but nothing happens.

If such a problem occurs, please first read first start instructions.

1. Check what's in tab “Settings” at the bottom of the Zennoposter screen in “How much to do” is not set to “0”.
2. Check what's in tab “Settings” at the bottom of the Zennoposter screen in “Maximum threads” is not set to “0”.
3. There, check that the “Proxy” parameter is set to “Do not use”. This value should be set even if you have set a proxy in the input settings.
4. Click button "Settings" in the top-left corner of Zennoposter, and then turn off "Resource Tracking".
5. Check the Log tab at the bottom of the Zennoposter screen. Perhaps there is some information there.

If all else fails, also check out this instruction.
