Captivate Trial Expired on first attempt to open

I am a CC subscriber. I downloaded and installed the Captivate free trial yesterday, and on the first attempt at using it, I received a message that my trial was expired. Would my subscription to CC cause this issue? I have scoured the discussion boards and have not found any helpful information. The virtual assistant has not been helpful either. It provided a link to a post resolved by someone who already had a valid license. (https://community.adobe.com/t5/captivate-discussions/captivate-9-trial-install-expires-after-only-1-day/td-p/8945068#sa_src=web-messaging) 
I am using Articulate Storyline and wanted to compare Captivate for a potential client. If anyone from Adobe is out there, it is very time-consuming and frustrating trying to get support. There is a lot of unhelpful information in the Discussions section. It is full of nonsensical comments.   Perhaps the motivation to engage people in the community for free access to Captivate is behind this?  
I would be happy to pay for one month, but I cannot commit to a one-year subscription without the opportunity to evaluate the software.
