Hi,
Please don't modlook a topic because you want a response faster, it is not what it is intended for and if it is abused in such a way we some times do take action as it takes away attention from more important matters.
As for your problem, it sounds like the import it self is fine, but your host is imposing a limit like a memory or timeout limit which hits you before the import finishes, which is why you don't get all the content.
I'm quite unfamiliar with the host in question here so I can't attest to which of the two it is, but I am quite certain it's one or the other and they are both things the host might be able to raise for you so you can perform your initial import.
