You need to clean the corrosion and closely examine the resistors, capacitors and ICS (and their connections) with a high power lighted magnifying glass. You can clean it with rubbing alcohol and a cotton swab.

You also need to add additional solder to the solder joints on the connector, desolder them, inspect the copper on the board (to determine if it's intact) and then resolder the connections. When you do this, touch the soldering iron to the tip of the connector pin only. Allow the pin to conduct the heat to the board. The copper on this board is VERY thin and VERY easily damaged. Touching only the connector pin will virtually eliminate the possibility that the board will be damaged.

I doubt that any of this will solve the problem but you may find a defective component or solder connection.

What error do you get when opening the file?

Look for solder connections that have deteriorated, damage to the resistor bodies and discoloration of the small SMD capacitors.

Did you try downloading it again. Maybe it was corrupted in the download and the copies you sent to others were corrupted. If you download it again from your email server, maybe you'll get a good copy.
