Error in VTI module in Alfresco 5.0.d

[thenetstriker]

I've just upgraded my Alfresco installation to version 5.0.d. With this version the problems with check-in function of the VTI module are fixed. I can now open my MS Word documents, check-out documents, edit them and check them in again without any problems. But there is a new error if I'am triying to browse all documents directly from Word:

- Start Word 2010 and click on file => open.
- Enter the base url of the VTI service. (e.g. https://server:7070/alfresco)
- The following error appears in Word:

HTTP ERROR 500

How can I solve this error?
Edit: This seams to be the url word is calling: https://server:7070/alfresco/_vti_bin/owssvr.dll?dialogview=FileOpen&FileDialogFilterValue=*.docx;*....

Same error when I try to access to the VTI service thru MS Word "http://< host>:7070/alfresco". Moreover the "edit online" button isn't available in share.

alfresco-global.properties :

vti.server.port=7070
vti.server.external.host=<host>
vti.server.external.port=7070
vti.server.url.path.prefix=/alfresco‍‍‍‍

I installed alfresco-community-spp-5.0.d.amp (http://docs.alfresco.com/community/tasks/SharePoint-install.html)

I enabled basic authentication in regedit: HKCU\Software\Microsoft\Office\14.0\Common\Internet: BasicAuthLevel=2

I followed this page to enable non-SSL connection: http://docs.alfresco.com/community/tasks/SharePoint-config-office2010.html

Did I forget something ?

Alfresco Version
