In 2003 when I first starting using Esprit I was given 2 post, one for my HiCell and the other for a Nakamura SC250. The HiCell was a .ASC file and the Nakamura was a .PST file. I'm able to make modification to the .ASC file but can't open the .PST file. If anyone has any idea on how to open this type of file please share. There are a few simple changes I would like to attempt to make myself. Thanks in advance.
