If your Sage 50 software message text is “Error loading current company file,” this could mean one of two things. One, there may be an issue with the company file itself. Or two, there could be the possibility that your system is unable to open the company files and the company files are missing after a server update. Before troubleshooting this error, it’s important to know what caused it.
