why is quick par making my life hell tonight?

[maca]

I have a good deal of experience repairing newsgroup downloads with quick par, but tonight I'm encountering a problem I hope somebody can help me with. I've downloaded a very large set of rars (app. 150 parts at 15mgb per part). I noticed as they were downloading that a few were a little short, but it appeared that I had more than enough par files to fix it. Indeed, when I ran quick par, it went through its calculations and said, "Ready to recover using 17 of 38 recovery files". Great. I started the repair. Ten minutes or so later, it ends with the message... "Ready to recover using 17 of 38 recovery files". OK... I try it again. Same message. And every time, it creates a new set of files to replace the short ones, files that are the same size as the good files, with extensions .1, .2, .3 etc added with each pass. Why is it creating all this stuff but not actually fixing anything? I've never had quick par tell me something was repairable and then fail to do so. Any advice? Thanks in advance.

I used to have a VERY unstable DSL connection by one of the US's main ISPs, who I probably shouldn't name. I finally switched to their new and improved internet offering. I had previously experienced something similar to you on a very large download of a foreign language film that I cannot buy in the USA. I found 2 things to help me to finally extract it.
1) My old, unstable connection used to drop all the time. Apparently a rather large number of my rars got severely corrupted because my connection dropped and when it got re-established NewsBin failed to completely recover the missing parts. I had to re-download about half or more of the files with my new stable internet connection. That got me enough good ones that the PARs could do their thing.
2) I am running Win 7 64 bit. If you are too, look for MultiPar. If you are downloading a really big file (bigger than DVD), MultiPar is a 64 bit par recovery program that works better on very large files than 32 bit par recovery programs.

I'm also running win7 64. My DSL is very stable and reliable, though. Even my news browser told me before the download that those files were a little short, but that there were enough pars to repair. Yet quick par keeps giving me these new files that are the right size but won't do anything. For example, if 010.rar is short, I now have 010.rar.1, which is the right size, but when I try renaming it by dropping the .1 and using it in the extraction, it says it's corrupt.

I will try multipar. Maybe it can handle whatever's going on here. Thanks for your advice. I'll also try rechecking those short rars and see if I can get any better downloads of them.
