Error - The document could not be saved. There was a problem reading this document (105).

I just registered and installed Adobe Acrobat Pro DC and I cannot save PDF files.

I decided to try the trial period because I was so frustrated with the lack of functionality in Adobe Reader.  I need to be able to sign documents, and even when DC reader works, it takes minutes to open a single document.

First, I uninstalled DC Reader.  That took about a half hour.

Next I signed up for the trial period.  I was surprised that Acrobat was so difficult to download.  I had to attempt a few browser tricks before I could even start the download.

After finally installing Acrobat Pro, I was unable to save PDF files.  I've tried multiple files and tried saving them to new locations, but I get the same error.

To add insult to injury, I couldn't contact tech support because I haven't registered my product.  (That sounds like an error I'd get back when people bought software in a box at the local office store.)

Please either help me resolve this issue or cancel my trial period immediately.  I have no desire to pay for a product that doesn't work and isn't supported.
