Error Compiling Digi ESP NET+OS with Connect ME 9210

I am running Digi ESP NET+OS 7.5 and I am getting a compile error:

Type undefined reference to `FCRenameFile’ [/mnt/cdrom/scm/TIS_Projects/Micro Ethernet/SoftwareEngineering/Digi_SRC/CME9210_Ethernet/Debug/…/FTPInterface.c] CME9210_Ethernet 1381 C/C++ Problem.

I think it might have to deal with the library fclntapi.h.

Can you create a new project via Digi ESP? does it build? if so recreate your project from scratch using this project as a starting point. If not re-install netos.
