Hi huatz,
It like that you are using the old version, can you download the latest build and try again?
Latest build download url: http://cutesoft.net/downloads/folders/21904/download.aspx
Delete the dll files and the whole "CuteSoft_Client" folder, then use the new one.
by the way, can you show me what path you set for the gallery store folder setting?
Regards,
Ken
