EPM Addin for Microsoft 10.0 - Cannot create Connection

Hello,

After installing EPM Addin for Microsoft 10.0 SP 25 Patch02 on Excel 2010 32 bits (I tried version .Net 4 for big volume and version .Net 3.5), I cannot create Connection:

* Connection Type : Local

* OLAP provider : Use XMLA to connect to a Microsoft Analysis Source (I tried also OLEDB Provider)

Connect ==> Application server : Datapump URL / Auth : Entreprise BOE Authentication for BFC

Next ==> User Name : Test / Password : xxxx

Log on ==> I choose the data source : (The list is displayed)

Finish ==>Nothing is displayed on the Cube/model list although the database contains the cubes!!??

Ps, any help?
