DOSBox DOS Emulator has encountered a problem

Hello,
When I try to launch my theme hospital, it goes to the dosbox emulator and the following error message occurs “DOSBox DOS Emulator has encountered a problem and needs to close. We are sorry for the inconvenience”.
I am running Windows XP Operating System.
Please provide any solution to fix it.
Thanks.
