We have a very big MS Publisher file (90 Megabytes) on a server and me and my colleague open it and modify it every week. Our pc's run Windows 98 and of course the MS Office suite with Publisher. Now we cannot save it anymore, the program hangs in both pc's and the file remains unsaved. I know it is a big file and there might be a network congestion but it never happened in the past 2 years. What can I do? I tried to reinstall Publisher but it didn't help.
