To Anyone aside from Michael following this thread,
We have been able to solve this "Time Zone Unknown" Error when trying to open a Report in the Method Report Designer. This seems to happen when there are issues with an outdated Microsoft Windows Time Zone Registry Key. In Michael's case, it was specifically the "Central Standard Time" that was causing this error, once we sent him a more recent Windows Registry key for this time zone, he confirmed Report Designer was working fine.
If anyone else comes across this same error and finds this Forum Thread, I have provided a link here to an Official Microsoft Webpage discussing this issue. The webpage will also explain how you can update your computer to fix this error.
If you do run into this error and the link above does not help you resolve it, or you find it confusing, please do not hesitate to contact Method Support for assistance. Support can be reached at 1-888-925-6238, press option #2.
