blocked files question???

I'm new to sharing files. I was downloading a file and my computer started acting weard and I paniced, so I blocked everything from being uploaded. It took me a couple days to correct the problem. I noticed I couldn't hardly download anything. I read the Q&A and I'm assuming people have blocked me from downloading from them. I unblocked everything but the download problem still exists. How do I correct that if that is the case?

What is the download problem? Will nothing download anymore? Try & explain exactly what's going on.

That option to block freeloaders is so iffy... I'm not sure that it even works at all. So I doubt you'd be suffering because users are blocking you!

Well, I start downloading a video file and it starts extremely slow and then stops. Now I attempt to resume and it never starts. I can click on a new file that is the same subject and it starts downloading.

Does a new search kickstart the original download, or do you always end up having to start downloading a new file?

Are you resuming the download from the download pane or from the incomplete folder? Have you tried clearing the download from the download pane, then going library > incomplete files & resuming it from there? Does that make any difference?

Do you see the firewall icon (brick wall)? How many connection bars do you see?
