Hi diegoterc3,
i did a write-up of how to get started in an other thread which might contain further information
https://www.eevblog.com/forum/altium/getting-started-with-altium-designer-12/msg126585/#msg126585(begin copy)
If you hope on somebody who can show you "How to Altium" you will be very disappointed. There will be nobody who knows everything about it and Altium has too many ways to do one thing.
1st register for a guided introduction "Live webinar" on their website, this is free and happens every week. You are connected via webseminar to an Altium engineer who gives you an 2h introduction. You can also ask questions during. This is very very helpful if you never worked with Altium
http://altium.force.com/eventsSearch for "Introduction to Designing with Altium" in your language and your Region.
Click on register and input your details. Half an hour before the Webinar starts, you get an email with the link to it.
2nd watch all the training videos on their website. ("Hello, Marty here!"). Every video is short and focussed on one topic.
http://altium.com/training/en/training-videos.cfm3rd Read the Getting Started Part of the Wiki
http://wiki.altium.com/display/ADOH/Getting+Started+with+Altium+DesignerNext thing, download the Tutorial and work it through
http://wiki.altium.com/display/ADOH/Download+PDF+Learning+Guides NEW linkAfter all that, the Altium Wiki is your friend. It is very well structured and even gives you hints.
After that, there are hundreds of tutorials on Youtube.
And after all that, you probably have to ask your company for a 3-day-course which is about 1500 $. (does not apply to you)
Also you might be able to squeeze a few infos from your local sales rep. The Altuim Support is very comprehensive and if you ask right he will give you the info you need and not be trying to sell you a seminar.
EDIT: This is a similar thread with lots of info
Altium- I am about to cry!!
