I also have the same problem. I use -maploadinfo with GW2 shortcut and it shows that mapload and modelload is not progressing for entire time (around 5 minutes of loading). Then game forces me out back to launcher with code of error message (Code=7:0:0:1026:101). I thought it may be problem of me updating client that was sth like 1,5 year old, so I removed *.dat file and started to re-download it. While launcher reached “playable” state I started the game and could play “fairly normally” (had to download map before entering it, but it was not disconnecting all the time like now, after I finished dowloading entire game). Problems like that started around yesterday (from time to time), now this problem prevents me from entering any map (but still can log into character select).
