Alberto, don't worry, the INS is a tricky little box and starts to develop its enjoyment after going through real pain ;D
See it like in those military movies, they first break you and then build you up.
There are some important documents coming with the Civa (look into the Civa\Docs folder), one of them is
http://img709.imageshack.us/img709/1105/insstatus.jpgSo "stops align at 65" is a somehow misleading expression as you might see then.
Please look up that (whole, not only the picture above) document and watch the digits described closely.The Civa unit speaks to you with these error codes and we have to make sure that you are listening and understanding what it says.
Also press and hold the test button (all lights come up then) every time
before starting alignment to cancel all error code in the units.
The remaining error codes are the ones to care about. Normally, there shouldn't be any before starting the alignment.
If it still stops the process, I assume that you have entered the initial coordinates somehow wrongly or just went from "standby" to "align" without checking/reentering them.
Please report back on this after reading.
