1: the hash is messed up on the package so it can't download anything. if you right click the package you can select reset package hash. Then try to run it again.
2: This is most likely the cause.
The package can't access the share to get the .reg file. You need to add the .reg file as a additional file so it will download the file along with the bat file. You will also have to adjust the bat file so it looks for the .reg file in the same directory as the the bat file. The file will be downloaded to c:\program files\landesk\ldclient\sdmcache\deployment_patches
