Help! Upgrade Error! NAV2009 RTC

I have upgraded the company’s navision software to 2009 version, but when I open the RTC client, it will pop up the following error : “The given key was not present in the dictionary.”.#### I have confirmed that 2009 version is installed correctly, because I can normally use the Demo database launch RTC client. I do not know how to identify the cause, can you give some advice to me, thank you!

Nothing constructive from this reply…

But more likely you’d better contact your NAV Vendor. To find out which part of objects when wrong during upgrade.

Thanks, but I upgraded it by myself , so I don’t want to contact suppliers.

I would check your config files for both the client and service tier to make sure that they have all of the appropriate key / value pairs. These are probably loaded via the .NET Dictionary class, which would give a similar error.

Thanks!
