Thanks for all of your replies. Let me clarify a few points.
The union of Roxio and Sonic has caused a lot of confusion for me. Although "creatorxe905u" doesn't exist on Roxio's sites, it apparently does exist on Sonic's. When I run Roxio Creator 8.2 XE, the opening "Welcome" screen automatically communicates with Roxio on the web and gives a list of sales pitches, feature articles, and tips that are all available. The first thing on the list is this:
"FREE upgrade for Creator 8.2 XE users. Click here",
and it links to this Sonic page:
http://docs.sonic.com/updates/emc9/creator...=31&kn=Easy Media Creator 8 OEM XE Generic&type=main
You can go there yourself if you want to see what I'm seeing. It looks offcial to me, obviously from SONIC and not from some hacker site. When I click on the link, I don't get a description or explanation of the download. I just get the standard windows download dialog, asking if I want to save or open the file. I have saved it to disk (562,355KB) and run AVG scans more than once on the file, which always checks OK. There is no filename extension- no ".exe" or other suffix. Just "creatorxe905u". It seems to be some kind of zipped file- When I scan it, AVG reports that it contains 7527 individal files. Since I don't know how to run or unzip it, I can't give any more info.
The original 8.2XE came with my Mad Dog DVDRW drive. I'm having problems with the program freezing in the middle of rendering a DVD image, and I was hoping that the free update would solve my problems. Since I only need to burn a couple of homemade DVDs, I don't want to spend the money for v.10 if I don't have to. I'm using XP Pro, not Vista, so I hoped the older version(s) would work OK.
Thanks for your further comments.
