SAP HANA 30 days trial - Problem with uploading CSV-Files via FTP

Hello community!

I have got a very big and strange problem with that guide at Step 4 - FTP and import your files into the HANA system.

- I am using FILEZILLA on Windows 7 as my FTP-Client.

- I logged in with the Username & Password, everything works fine

- BUT: I can not load my *csv-Files into my folder, which I created, there is always the following error code: 226 Transfer done (but failed to open directory).

=> The strange thing is, that I CAN load my *csv-Files in any other existing folder, but not in my own!??!

The Name of my folder is: S0002866913

Thank you very much for helping.
