I recently downloaded and tried out the Shareware program 'Rulers' for Windows made by Omnidea.
I thought I'd buy it, but in clicking on the 'Buy Now' button in the program, it took me to an error page.
There was also no seeming way to buy the Windows version anywhere on their website.

I contacted the software maker and asked how to purchase it, and it turns out they only make it for the Mac now - you can't buy the Windows version and it's not being developed any more.

So, I'm stuck with a crippled shareware version of the program and no way to purchase or upgrade it.
Can't even seem to find a cracked version.

Does this sort of thing happen often?
