Hmm,reminds me of....Creative Labs,doing the same thing (with me)...about it's "Live! 5.1" sound-card, when I 'upgraded' to Vista.
Creative's 'response',was.......
"Live! 5.1 and,earlier versions of Creative Sound-cards.....have reached the End....of their 'Service Life'."
Incredimail's done exactly the same!(With it's software!)
Are you 'absolutely positive'....that you tried 'every version' of Incredimail?
(Personallly,I don't think so! Why do I say that?........You stated(your own words!)..."You tried older versions and tried to 'reboot' from a back-up disk.")
I will believe the 'latter', not the 'former',okay.
There should be a 'version'(of Incredimail) for ME....in their "Archives".(Did you look,there?)
The only way that there is no longer a 'version' available,from their web-site...is that Incredimail itself had 'added'....the 'non-availability clause'......to their "Download" Section.
With ME!
It, too, has reached the end of it's 'service life'!
Even though people are still using it!
Please,accept the 'fact of reality'....and,move on!
If you really want Incredmail back, do as PZ has suggested?
I will suggest it,too,because I am in agreement with him.
Upgrade!
Technology has finally caught up with you.
You are as 'out-dated',as your computer is!
The software is starting to 'fail'....no further 'updates'.
It may sound 'nice'...that you have a computer still using ME.BUT!
And,that's where I will leave it.
