I cannot connect to my other computer, Error constant: THE SCREEN can not be captured at this mome

I try to connect to my other computer in another city location at my brothers house.

It keep showing this error,

THE SCREEN can not be captured at this moment. This is probably due to fast user switching or a disconnected/minimized remote desktop session.

I can connect to the computer BUT cannot click on anything to work AND Then that error pops up.

I have tried all day for 2 days and still cursor will not click on anything to work

I have rebooted my comp and that computer 10 times already and still the same pop up error comes.

I don't want to wait another week until my brother to return and we try to figure this out.

So are there any solutions? Does anyone know?
