I am still currently downloading STO but I require to close my cpu very soon as I type this.

Will it resume downloading if I interrupt the downloading sequence?

I really want to play Star Trek Online but for now, I will have to interrupt the downloading.

Is this nadwidth heavy also? I have a limited internet each month but am willing to download it.

Thanks if anybody can clear this up ASAP

STO utilizes Pando Media Booster as a download mechanism for the client. As it acts something like a one-way P2P client, it should be able to pick up where it leaves off.

As for limited bandwidth usage, I would highly recommended uninstalling Pando from your system as soon as the download is completed, as it has been known to use bandwidth at much the same rate that tribbles reproduce.
