Hi I am using Chem station Edition software, till yesterday all my run, data acquisition was normal. Today when I started a sequence of 15 tubes, it started well and got the result for two, checked that in offline data analysis window. But when it started the third tube i am getting "Data file name XXXX not valid" and "Data Directory not created bad path name". The tube is running but i couldn't see the result after in the offline data analysis window. Can any one help with this please.Thanks in Advance.
