Hello Friends
According to my post about setting back the systemdate to avoid periodly login to RockStar at gamestart.
I wanted to let you know that this also works with the new Launcher.
So if you start your game offline and the startbutton in the launcher returns to the 'unpressed-shape' and the game doesnt start, just set your systemdate back to around the day when you last logged in to RockStar. The game will start now without waiting for an online-connection.
Dont forget to set back the date to current if the game is runnung, to avoid trouble with your savegames.
To change the date under windows, click on the clock on the desktop-taskbar and choose 'change date and time'.
Again choose 'change date and time' in the popped up 'date and time'-window.
After the game is running pause it and press ALT&TAB at the same time to switch to desktop, where you can set back the date to current.
I hope i could help to disstress your gamestart a little bit with this 'hint'
