We've released version 1.0.3 of the Creator software along with an improved profile specific to the MakerGear M2 printer. Follow the instructions in your confirmation email to download the latest release. The changelog is visible here (http://www.simplify3d.com/changelog/).
To load the new MakerGear M2 settings, just select the "MakerGear_M2_PLA.fff" profile from the dropdown list
I would suggest uninstalling your current version and then re-installing the new update. All activations should be maintained so you won't need to bother with that ever again. If you really want to, you should be able to install the new version on top of the old one (since they will be installed into different directories), but I probably wouldn't suggest it.
Let us know what you think!
