i read in the pc updates that the cloud server for FNV would be down. so i was wandering when it would be up again and when it is back up and running, how would i go about using it so i can play my game between 2 computers without having to transfer through a flash drive? is steam involved and what are the steps to doing this?

Until issues are sorted with the Save synchronization, the Cloud Service with Steam has been disabled. There has been no announcement as to when it will return, if ever.

One thing I will caution you on, if there are mods on one build and not the other, or the mod mix is not exactly the same between the two builds, you will hose your save going from one to the other and back again. Vanilla Games are OK. Not sure as to how much effect the different pre-order bonuses will have on this, but that could be an issue too.

can i use the same disk and cd key to install it on lets say 2 computers? that way i can play it on my desktop and my laptop?

so basically if i use mods make ABSOLUTELY sure im using the same exact mod build on both computers.
