There is no need to contact support...unless of course you think you need their help with the installation.
All you have to do is reset the camera to factory settings. Use a paperclip or something else that fits on the reset hole located at the back of the camera next to the WPS button, press and hold for 7-10 seconds ( you should see the power light turn red) and release.
Your camera would be sent to factory settings and you can start setup from the beginning at this point.. Let us know if this works for you...
