From time to time we will see device instrument communication errors within third party software (like GMG or CGS). Usually the problem is a conflict between newer i1 drivers installed on the system (e.g. with latest ProfileMaker 5 software) and older drivers included in the other software. To fix this problem, just copy EyeOne, EyeOneIO, and EyeOne_iSis frameworks from the ProfileMaker (version 5.0.9 and newer) application folder and replace them in your third-party software application folder. The new frameworks can be obtained by downloading and installing the new version of i1Diagnostics 2.5.1 as well.  Be sure to relaunch your software after replacing the files.
