Hello Stu, I'm very glad being here again taking with you after such a long time! What to say if not 'Wonderful!!!' when thinking about the fact that among all the versions I could download and build, I've caught a broken one... I'm a lucky man!
That said, I confirm to you that I've built aMuleGUI 10786. Apart from the fact that I always rebuild aMuleGUI to match the version of the daemon, this time I couldn't do anything different even if I wanted to because aMuleGUI 10494 don't work with amuled 10786 because of a protocol change.
The password is right but it rejects any connection attempt complaining about it being wrong, I don't know why. I'll build another SVN soon (I guess that everything including and past 10788 is fine, isn't it?) and post here the results ASAP. Have a good day!
