In reference to working offline message its key to see what you're running alongside Xolox. Some users like to run two different p2p programs at the same time (i.e. Shareaza and Xolox together) Since just about all p2p programs use the same port to listen to the network you're going to run into problems if you try running two p2p programs in tandem.

Also, could Team Xolox please let us know the current build alongside with the version number on the homepage? I typically don't update my version until I see the next number, and end up missing out on each build because I didn't know there was a new one and I don't want to miss out on anything! Thanks!
