Replacing DI software is definitely a move in the right direction. If you upgrade to MeasureMax+, which I strongly recommend, make sure that you get the latest and greatest which is Version 6.1. This is great software and has capabilities to do a lot of the upper level work which is required in today's quality world. You might be able to purchase just MeasureMax (no +) but don't do it. The few extra bucks required to get the + is worth every dollar spent.
