Syntax Error in Microsoft SQL Server

Hello experts,
I have created A trigger using SQL server 2000′s Enterprise Manager (which does not suffer from the bug).
When I try to open the trigger much later using Microsoft’s SQL Server Management Studio, the trigger fails to open and I get the following message:

Script failed for Trigger ‘TEST’. (Microsoft.SqlServer.Smo)
Additional information:
Syntax error in TextHeader of Trigget ‘TEST’. (Microsoft.SqlServer.Smo)”
I am looking for some help in this regard which will be fully appreciated.
Thanks
