can't open a wsxz package with Trados 2009

Hello everyone,

I have a wsxz file to open with SDL Trados 2009 and when Try to import the package, I have an error code -2147220888 : The termbase definition contains two fields with the same name at the same level.
I don't know what to do. The client wants me to work with this extension file wsxz.

Can someone help me please?
