I always get the following message when I open my project; and in this case, sometimes I can not add anything new to my sch design. I had tried to create a new project, and it is ok at the first time; but when I re-open my project, I get the same result. if making the operation of "Cleanup Project Files", I found that it is error when "Translate". help me please!
