I installed D2LoD and when I want to open Battle.net then it shows "checking version" and next crashes connection "Try again in few minutes". Can anyone help me? Is it possible that my cd-keys are banned? I wrote to blizzard but they answer with (link to topics) and their help is hopeless.

Try again in a few minutes

If your keys are banned you would see that i believe.

It took few days and problem solved itself.

this happens to me from time to time. if i have a login issue ill cool my ip by waiting 8 hours. if there is any issues after 8 hours ill wait 72 hours. if any other issues after 72 it means you could be restricted for 2+ weeks. but this only happens if you used a vpn, bad ckeys, in game spamming, spamming spells, join/exit too many games.

if cdkeys were banned it would give a ban code.
