Yes to my inexperienced mind it sounds as if there is a security issue. You might want to check the little black boxes configuration to see if the security of it is compatable for your system. But then again I may not know a thing and barking up the wrong tree.
OK I will try this again. For some reason some of my posts are disappearing.
On Solo I and Solo II How far have you gotten. I have gotten out to the 20s and survived to live another day. It is when I go to the east forest that I end up dying. Small dragons are not fun. I am level 16 in this and bought all maps except for the unknown area that is 9,000 alone. I hope to get enough tp to head to east city and the kingdom city to see what better equipment I can get there.
In Solo II I am second level and doing good. I am 1,500 experience from level 3.
