I've purchased a License of Alibre when it was very cheap, but I still wasn't able to use it.
First they remove from the design version the 3DM import. No Moi No Party!
Then they don't support Windows 7 for previous version. I have a license that doesn't expire but I don't have the OS for use it. The worst experience I had with a software (along with Windows ME maybe....).
