Model generation error after installation BPC10.1

Hello,

I'm trying to create standard model with BPC10.1, but during last stage of generation I get a following error :

An exception of type CX_SY_OPEN_SQL_DB occured, that was not caught anywhere in the call hierarchy. It was not handled locally or declared using a RAISING clause.

I work with NW7.4 SP 0008.

Does anybody had a same issue after installation of BPC10.1 ?
