I try to help you when I can, but I have noticed that a lot of your questions could be easily answered if you'd just take the time to google. Of course, the same can be said for a lot of people who post on here.
Another thing I've noticed is that you seem to go off 1/2 cocked. You either read something or are told about a program, then you download & try to install it without reading the requirements. For example, you just wrote "I downloaded a free pdf creatoe I found I need XP or vista". If you would have read the requirements ahead of time you could have saved yourself a lot of grief. By now you should realize that Win9x/ME are dead ends & have been for a long time. There's very little *modern* software that supports it anymore. M$ stopped supporting WinME at the end of 2003 & stopped releasing updates for it in 2006, along with Win98. The longer you stick with it, the harder it will be to find software that will work with it, not to mention the security risks.
I realize that your system specs are too low for a modern OS, but you should be able to run Win2k. At least that would give you an NT based OS & would extend the useful life of your computer a little longer. And most of the software that you've been dreaming about that won't work with WinME *should* work with Win2k.
If you don't wanna pay for it, Windows 2000 Professional is available thru the torrents. Get yourself a bittorrent client such as utorrent, then use the search engine at isohunt.com.
