Apparently, your problem is infeasible. This message comes from presolve that detects the infeasibility. It is very likely that this has nothing to do with CPLEX but you have an infeasibility inherent to your model or your data. Either the system you are modeling is infeasible, you did a mistake in your model, or your data are wrong.
To analyze the infeasibility, I suggest to run the conflict refiner. In the interactive, this would look as follows:
read yourproblem.lp
opt
-> will return infeasible
conflict
display conflict all
The conflict refiner will extract a small sub-problem from your model that is already infeasible. By looking at this small, you can probably find out what is going on.
