TBH even if you could sell/transfer the licence, which AFAIK you can't, I'm not sure that you're going to find too many willing buyers of X1 anyway.
That's a good point. X1 was a rough patch.
To the OP,
The EULA does clearly state the software
can not be re-sold.
The wording in the EULA is basically.... "
you didn't buy the software, you merely paid to use it". A lot of people don't always look in to purchase agreements when buying software so its an honest mistake.
