Stuck on a mission, pls help!

[Funkman]

So I am at the part of the story where Trevor kidnaps the gangster's wife and he and Micheal hide at his trailer.

I have done the bank job where you use the military hardware to defeat the cops, then I have done the next mission where you rob the train.

Now the next mission to trigger is an FIB mission, and you have to go to this remote place near the water to trigger it.

Problem is, everytime I go there the following message pops up "MIssion has been disrupted, return later to start the mission".

I have slept and come back, returned as both Michael and Trevor, and the same thing happens.

I fear this is a bug and I cannot progress.

Anyone else have this happen and now how to fix it??

Thanks.

I'm guessing the mission you're on is Military Hardware. My only guess as to why you're getting that message is you have a wanted star. If that's not it then I don't know. I know that what I did was go to the location and set a trap with C4 and waited for the convoy to arrive, blow up the lead vehicle then take out everyone else.

I remember having the same problem with this exact mission. I don't remember what was causing it but I remember the workaround I used:
Call a cab, tell the driver to drop you off there and then skip the journey, so you get straight to your destination.
Do this and you should have no problems starting the mission.

You are talking about the story mission monkey business. The mission disrupted message happen to me all the time. What I do when I get this message is to turn the car around and go back up where you came from. Then go to the the dock and start the mission.
