It depend on how many bsources you're downlding from. It won't be unsuccessful. Even if it's only one source with the file. All you need to do is wait until they come online again!

But please don't do something silly like use the Force Resume button. And even more effective & healthier than the Resume/Find Sources button is to manually search the topic again!!! No. 1 most effective way to find sources!

2/3 to 3/4 of the time I open LW my incomplete downlds start by themselves. I'm patient. You need to allow LW to settle down before doing anything. In fact 2 days ago I opened LW & didn't do anything (not searches or anything at all. Just oopened it & forgot about it.) Just had it hiding in the background. After 40 mins I had a file downlding from 4 sources at 27 KB/s (which is my max dwnld speed) & 15 mins later had another from 2 sources. I also had people uploading from me which is very important to get these types of results.

Here's some hints you might find helpful: A well set-up LW can start to automatically continue its dwnlding after it's settled down perhaps 2 out of 3 times you open LW. Optimising LW & Maximising Uplds & Dwnlds A (1st post only) & also Part B which is even better & last & least are search & dwnld hints. The latter one I've been thinking about re-writing for some time. That's just for playing it safe. eg- I show all speeds & qualities.

I didn't use LW yesterday. But today I have had LW running for a few hours. But I haven't done any searches or anything. I had 9 files downlding (I paused some) & most from multiple sources. Even after resuming my paused files (still have some paused), they continued with multiple sources. This is even better then 2 days ago. I had to very quickly pause the files b/c there were too many attempting to downld. (My fault due to prefs settings but I like to have that flexibility.)
