Hi,
I closed Railworks/Steam after working on my route for a while, and decided to take rest..opened again after 3-4 hrs and now suddenly steam says to install railworks..There is no play button..I did not change anything.How can I revert it back..is this happening to anyone else...

Reboot is not the same as Restart. Shut down the computer so you have to push the button on the case to start it up again
