My subscription ended last month. I did not renew because i wanted to use the free trial version up first. I plan on renewing after the trial runs out. It says my current account is for the creative cloud free membership, but when I try to use the software it doesn't let me.
The CC was cancelled on 27th February 2015, I am not sure whether the trial can be used on the same ID for the same product. You can try uninstalling the CC then installing & activating the trial.
