EXPORT issue, can't export

Hello,

I'm migrating between versions and servers. So I need to export data from Docman in order to import it back. When I click on export, things start nicely then I have this error :

Table 'petitpoisson_test.xsrg3_docman_document_contents' doesn't exist of the following query : SELECT * FROM `xsrg3_docman_document_contents` LIMIT 0 , 300 

petitpoisson_test is my db and xsrg3_ is the prefix for my databases, this is correct. But the docman_document_contents does not exist. What can I do?

Thanks in advance…
