Sorry to hear about that Juan. It sounds to me that, regardless of your experience in that department, things were moving along very well and you were pretty much on top of things. It seems lame and disrespectful to have someone come out of nowhere and request you be taken off of a project like that. You would think that a company that cared about it's employees would atleast take the time to talk to them about any issues that were begininng to come about instead of blindsiding them. It may be best to go to HR themselves and find the whole story behind what happened. It's most definately your right to know.

I hope everything works out for you. Keep us posted on how it goes. Just remember there's always a silver lining and something great could come as a result of all this.
