I messed something up in the last update; there’s a function call that results in a crash on start-up. The issue happens if Aion is not running when you start the meter.. my bad for not testing it properly ( I only checked with Aion running).
If you are getting the error in the screenshot below, just redownload the full installer here: http://rainy.ws/download/ I already fixed it and uploaded the patched version.
Now it’s working fine. Thank you!
