A connection error has occured

[Agnor]

So here I have also, I explained.
A great evolution, I went to start-up duel
The 32-bit computer is old, I do my tests above because it worked fine until now. But for this test it goes to 1-2 FPS for about 20 sec to load the duel which returns a "Connection error" on 64bit computer (Intel Core5) which has already instructed the duel.
Is it possible to wait for you to try Friday with my brother's computer? Or do you think that it is always the same problem?
