unity 3.5 pro activation

so I have my pro activated on another computer I don’t have access to anymore. I can’t re activate my 3.5 pro. I tried online activation but it said my activation limit has exceeded but on my account, the number of devices say i have 0 activation.

There doesn’t seem to be an option for manual activation . How would I do that? When I install Unity 3.57, I chose the free version, and enter in serial manually, but it says the version of Unity has already been activated then directs me to an option of manual or internet.

Manual activation keeps giving me an option to save or load license and that’s about it. Can I generate a license file?

I have tried emailing the guys at Unity but no response. Any help?
