Thanks for the suggestion. I actually did that :-)
I believe the problem was the size of the ZIP files. I have 2 zip files that are 3+ & 5+ GB. In YPP it causes the program to crash. In JBinUp the 5+ GB file appeared to post but was not found on the newsgroup server. There has to be a file size limitation. I want to say it's 2GB but i am not sure. In The future i will have to RAR up the large zip files.
