So my brother has GW2, and I wanted to try it out on my laptop to see how it would run before buying. I copied all the files (including the 16.5GB .dat file), but when I run the app, it tries to download the whole .dat file. I really don't want to wait hours for the update, but I can't find any way to make it recognize my .dat file. Any ideas? I've done this with GW1 before and it worked fine. I also googled it and it seems other people have been able to with no issues.
I'm not sure either, I've copied mine over plenty of times by just putting it on an external HDD, run the GW2 setup, close it after it's finished and the launch comes up. After that I just copy everything over and launch the game... O.o
