Printing Software

What is a good up front software like repetier host to run the printer? Im having issues with repetier just suddenly loosing connection with the printer and "encountering a problem" and shutting down. I've re-installed several time with now luck so Im going to try something different and either confirm or eliminate that being the problem. dosnt have to be free but I would like something that at least has a free trial. Ive tried installing replicatorG and its not installing (some drivers are not installing for some reason).
