Transfering a 160Mb resold account

Hi

I have a customer that needs to transfer one of his accounts(about 160Mb) from his OldHost to my Server...
So he gave me the IP, User and Pass

I went to WHM and used the "Copy an account from another server with account password", because offcourse my customer doesn't have root password nor SSH access.

WHM started the proccess but it stoped in the "Creating archive..." step.
It kept there for while showing progress until suddenly stoped by showing done in the IE status bar.
Si I then checked but there wasn't any new account in the list.

So I tried with a smaller account(no more than 20Mb) and it transfered smoothly
The 160Mb account has more than 300Mb of space.
His CPanel is kind of old as it only gives links to Backup and no Remote location option... unless the Vortex skin doesn't allow it.

Any toughts about this..?
Is very urgent

thank you

P.S.
This was the last step..

pkgacctfile is: /tmp/cpmove-file.tar.gz
