I've tried everything and im still having the same problems, downloads getting to a certain point then stopping or going backwards.

Anyone else still having similar trouble?

I'm having exactly the same problem. Yesterday I updated to Limewire 4.16.6, and I started downloading three movies. (So unlike retro's situation, they hadn't been In Progress between Limewire versions) Two of them finally got to 100%, and stopped. I read in the forums that I should restart Limewire (this has worked for me in the past as well) so I restarted the whole computer and when I reconnected to Limewire, the two that had frozen at 100% dropped down to 75% and 81%, respectively.
They have now been "downloading" at over 100Kb/s for the past hour, and the percent hasn't moved at all! The one that's at 75 sometimes moves up to 76, and then drops back down to 75 again.
I've tried re-searching the items, but to no avail.
BTW, I'm in Canada, not the UK. Anyone who has had this problem as well found a solution? Should I restart the downloads? Is it a problem with my computer/program or the actual files?

I tried downloading a song just now, and it worked fine. Maybe just these files?? But they work as movies when I preview them...

I've tried restarting the downloads that got stuck and it made no difference.

I was able to download a few full movies last weekend. I had about a dozen on the go at the same time and started the downloads on Thursday night, I had to leave my pc on overnight and all through the Friday to get the movies I got.(about 6) I then switched it off on Friday night and back on on Saturday morning, but they made no further progress, a few of them were in the 80% region as well. So it looks like continuous downloading may be the answer, which will have to be a weekend thing for me as I won't leave the pc on when I'm out of the house.

That may be it. I cancelled all three movies that had stalled and tried downloading only one from the start(but a different version/size/name, etc.) It finished successfully in one sitting. i haven't tried any more since then, but I will this weekend.
I just remembered that i changed one or two settings in the middle of the downloads that stalled, including the folder that files would download into. It said the changes wouldn't take place until I restarted limewire. I don't know if that was a factor. Either way, I hope it was just a one-time thing. All three are cancelled now and I'll put it behind me until it happens again.

I've just finally been able to download a video file, but as the last two posters have said I had to download it in one go, from start to finish.

So that must be the problem, we cant switch off limewire while a file is still downloading as then when we re start limewire it'll be stuck.

Why is this happening tho? because with the last limewire before the update that was never a problem.

Even then I'm still getting a few files that are stopping at a certain percentage and going no further.

Thankyou very much birdy, i would very much like to go back to the last version of Limewire.

Briiliant, i've got the old version back now and my downloads I lost before are downloading like a train now Thankyou Birdy, I love you

Retro, let us know if your movie downloads continue the next time you switch your pc on or if they're still stalling.
