I was trying to download 590MB file and it got to 100% downloaded. But then it starts veryfing file content, wich doesnt stop at 100%, it just goes on 187 or more and then it goes back to downloading with 99% showing on download progress. When it gets to 100 it goes on with veryfing to 187+ and gets me back to 99% downloading again.

So it is stuck in a loop. I am new to LW. Is there any way to get this file or should I just give up. It is a big file, I wouldn't like to drop it after completing the download.

That's an odd no. If LW detects there's something different about the file from the moment it 1st started downlding the file, then it will try to re-downld that portion again. It will do it for a maximum of 6 times before giving up.

is this file a movie ? if yes.. what extension does it has?

No it is a zip file. There should be iso file in it. I had no problems downloading disc1. Now I am trying to download disc2 out of2. But where does LW place the file. I can't see it in shared folder. Is there anyway of getting the file before LW confirms it as completed download.
Maybe I should leave to verify for 6 times. I am not sure how many times it did veryfing.

go to Library -> incomplete files (you should see your file here) and then hit Explore. I recomed you that you first scan your file of viruses...before any other operations (hope it will help, but thinc that the file is corrupt...) if everything OK than extract the ISO from the zip.... good luck

Ok, I left it to work for almost an hour then I got a message that lw detected a corrupt file and dowload ended. And the file was indeed corrupt. But thanks guys for your help.
