HI All, I messed up my call cost file, and I really need to start it from scratch. Does anyone know were in the server I can delete the information to upload a brand new file instead? It is not possible to erase the mistake manually since there are more than 10k cost lines to delete. I even tried to change the lines in the XML to replace the information but it does not erase the information to be replaced by the invalid data I have provided. Thank a lot for your help!!!
