Rainbow 6: Las Vegas

[BuffBot]

I know this isn't a MMORPG, but I figured if anybody could help me it would be you guys. I'm stuck. I am at the scene in the Nevada Dam, scene is Spillways. The mission is to Hack the backup computer system (after you took the worker to the other system). Well I am having no problem getting to the backup system, but everytime my guy starts hacking, and I am holding off the tangoes it tells me I failed to hack it in time. Now I have done it as fast as it can be done and I get this everytime. Is there something I am missing? This is getting frustrating lol.

Nevermind I figured it out. Well not really but I passed it. Apparently sometimes it gives you enough time to hack the system and others it doesn't lol.
