How to start the ARC story missions? Thread - Uplink OS mod for Uplink - Trust is a Weakness

The way I remember it, you had to hack into the ARC Central Mainframe and deliberately get caught, after receiving that one mail which tells you to hack into there. Because when you don't get caught, they don't write you.

Well... I just did that... but instead of getting a new mail, I got a game over. Something I am missing here?

Nope.
You need to wait to receive the dead agent e-mail. At the end of the mail you will see some credentials for the ARC Mainframe.
Under a bounce path, connect to ARC Mainframe, unlock the Cypher, the Voice Detection and finally when you are at the login menu, click the credentials written below, like when you connect to the Admin Menu on ARC.
Those credentials won't work but now you need to disconnect from the Mainframe and go clear your logs.

ARC will contact you after a number of days so don't hesitate to do missions or just skip the time at x3.

I was wondering if the "storyline missions" were gonna be in this, but, just wait, after about, I think 7 in-game days, you get a email to try to hack into ARC and find files.

Tip: DO NOT ACTUALLY HACK INTO ARC, JUST USE THE CREDENTIALS GIVEN IN THE EMAIL AND LEAVE, IF YOU ADMIN HACK INTO ARC THEY WILL ACTUALLY ARREST YOU!

You actually don't have to wait on the email from the dead agent. Once the news article about him pops up, you can hack into the ARC Mainframe, check the logs, and carefully trace the logs back to his personal computer. Hack into that, and you can find the email sitting there waiting to be sent out, along with a particular file that, if you grab it, will start the clock ticking until ARC tries to recruit you.

Will Arunmor contact you if you'll do this that way? Or you can do only ARC missions after this?
