Tigo issues with Program changing nominal values

Hello everyone,

so, I am new to this company, and they just bought 2 brand-new Tigo CMM's and had an outside programmer create the first sets of programs for the machines. what is happening is when we have a crash do to miss aligned parts and restart the programs the nominal values change and have cussed many more problems. the programs are lock out with Read-only protection, but the nominal values are still changing. I have made backup copies of the programs and when I load those programs the values change as well when I start the program. this looks like it is only happening on one of the Tigo's, any help would be greatly appreciated.

thanks
