Acrobat Sign In Crash

I purchased an authentic perpetual license for Adobe Acrobat 2017 Pro and am waiting for it to be delivered, while using the free trial in the meantime. The program installed fine and I was able to use it without issue on my system for several hours before it randomly crashed. Now whenever I open it, I am stuck in a loop of signing in, activating my trial, and seeing the program open for half a second before closing and reopening the sign in prompt. No dialogue is appearing to indicate that the program crashed, but in event viewer I have found the following message:

There are dozens of identical messages with different timestamps and report IDs. 

I know 2017 isn't up to date but it was working just fine for several hours so there shouldn't be any incompatibilities with my system. And no, I can't afford to spend hundreds of dollars a year on a subscription service.
