RMQ IMPORTER : Link TS to Existing TC

Hi, 

I have read similar cases but their solution does not seem to work for me...

I have a Test Case of ID 39 in RQM. 

I want to import a Test Script to RQM and to link it to this Test Case.

I use Word RQM Importer (great tool by the way !)

I try these two line in my config file

testscript.testcase=LinkExisting("urn:com.ibm.rqm:testcase:39") 

testscript.testcase=Link("urn:com.ibm.rqm:testcase:39") 

I import the test script (manually or directly on the server) with sucess but no links are created...

Is it a bug or am i doing something wrong ?

Thanks for any help.

Damien
