Yoyager Scheduler tasks not running

I have two issues: 1) .bat files that are added to the task list are not working and 2) file transfers are not working. I'm on the verge of scrapping my attempts to use what otherwise looks like a promising application. The .bat files run fine when executed from the command line. I am running version of FTP Voyager on a Windows 2012 R2 server. The .bat file contents are:

Net Use Z: \\ocfs1\mailbox

COPY "Z:\FTP\SCHeadwear\Out\*.*" "C:\folders for transfer\scheadwear\out\"

DEL "Z:\FTP\SCHeadwear\Out\*.*" /Q

Net Use Z: /delete /y

I'm not crazy about copying the file to be FTP'd to a local drive, but it also appears that FTP Voyager has trouble with mapped drives (I guess my 3rd issue).

Any help is appreciated.
