Mobilink Transfer Utility Error Message

Hey
I’m using Mobilink File Transfer Utility. I was downloading and creating a remote database, when an error appeared on my screen.
This error message showed up when I tried to download a file :
mlsrv12
<Main > [-10249] Could not find file transfer root directory: ‘C:mlfiletransferDL’
It was the first time I encountered this problem. When, I started the MobiLink server with the -ftr option, it normally creates a root directory for the file to be transferred and creates a subdirectory for every registered MobiLink user, in our database. I noticed that every time I start to use it, in downloading files, this error immediately shows up.
Can someone help me fix this problem?
Thanks
