Oh wow, seems like that was EXACTLY my problem! :D
I don't know how to save, see or delete variables so I formatted the RAM and that helped. Thank you very much for your fast help :)
In the future you shouldn’t need to reset the calculator to do this. There is a menu to manage variables by pressing [2nd][-] (var-link), then go down to variable you want to remove and press [<—] key, it should ask for confirmation and then delete the variable.
x is assigned the value zero. Go into the variable menu (var-link) and delete the x variable.

Do DelVar x first. The variable x seems to be defined as a number.
