sshaggy got me on the right tracks but only worked the first time loading before resetting back to default. So here is a detailed guide for anyone unsure. Step 1: Open Technic Launcher and open Voltz options panel by clicking on the cog under Volts image on the left side. Once in Voltz options click "Open Folder" Step 2: Search for "Mekanism.cfg" - You maybe able to do this on windows start bar and skip step one. Location is "\AppData\Roaming\.technic\voltz\config\Mekanism.cfg" Step 3: Open the folder "Mekanism.cfg" in notepad or your personal favorite text editor - I shall be using notepad ++ Step 4: Once open look for "UpdateNotifications=true" now change it to "false" as shown below. Once you have done that SAVE and exit. Step 5 - This may or may not be needed to do. Like step two find "Mekanism.cfg" and this time right click and go down to "Properties" as shown below. Step 6: Once in properties trick "Read-only" then "APPLY" then lastly "Ok" as shown below. Step 7: Lastly Reopen Technic Launcher and play!
