You need to know Japanese or use translator to translate words you don't understand.
Read the manual that came with program, search google to find answers to fix any problems.
It depends what the problem is. You might want to try calling the company's support line if they have one. Otherwise, try looking for an address to send a letter.
First of all, you must locate the help files. If you do not understand Japanese then you will not be able to fix this. I recommend e-mailing the editing software's company.
