So what is that mean I tried everything can you help me with this .

Unplug the scanner from the PC.
Remove the software that came with it (uninstall)

Reboot.
Go to epson's website and downlod the software/drivers from there. Re-install.

Then try again.

*Only plug the scanner in when you are told to. NEVER before you run the driver setup

Correct ;) I guess I just assumed they would follow the directions :)
