Problems with big files

My XP SP3 Machine seems to loose the connection to the My Book Live. I just received my new 2TB model and started transferring files when the transfers suddenly started go belly up. first I suspected file size. but now I get “network path does not exist anymore” (translated from Greek) with the network share just open, after a while. I also got a new small Gbit switch to connect the NAS to my computer. 

I am a bit lost, as I wanted to ofload quite some files from my internal drived, in order to upgrade XP.

Any ideas?

Try using another Ethernet cable, you can also try connecting the my book directly to the PC or using a static IP.
