ECC 5.0 IDES - EndFastLoad -Error

Hi

does anyone know, what this error may cause? I attempt to install DB instance for ECC 5.0 IDES and get this message and the installation process is stopped.

(IMP) INFO: EndFastLoad failed with <2: Bulk-copy commit unsuccessful>(IMP) ERROR: EndFastload: rc = 2

(IMP) INFO: ExeFastLoad failed with <2: BCP Commit failed>(IMP) ERROR: ExeFastload: rc = 2

Please help!
