SSP2.0 FTP Server


I have implemeted a FTP Server with SSP1.7.8 and it works without problems.
After an update to SSP 2.0 I can´t access the server with filezilla. The software chrashes (BSP_CFG_HANDLE_UNRECOVERABLE_ERROR(0);)
I make a new project for the S7G2 SK with SSP2.0 and there is the same problem.
I have no problems with windows FTP comand line tool. It is possible to conect, upload files, list the dirrectory, create a directory...
Does anyone know this problem and a solution ?
