I just downloaded a copy of freeoffice on another distro and noticed they no longer ask for an email to send you a registration key--it just installs like normal via software center or using gdebi.
Also a couple of Textmaker tips:
Under Tools-Options-Files menubar you can set default format for Textmaker. I set to docx for Textmaker. Under that same settings area you can set the default option to return to your last position in Textmaker within a document, as well as how many minutes to save the document.
Under Format-Character on the menubar you can set your default formatting. I like it to default to 12 point font instead of 10 point. Use the 'set as default' option, but make sure you tick the box enabling default to it on all documents, not just the current document.
On Freeoffice, Textmaker, a big weakness is no default word counter, but if you right-click on the status bar at the bottom left of the page on Textmaker and then check/tick statistics you will have a floating word count box that you can move where you want to on the page. I generally move it up to the top right on Textmaker. It may disappear if you update Freeoffice, then you just repeat the previous steps.
I mostly use Textmaker so will throw in another tip for it. Under the abc spelling icon at the menu or ribbon you can drop that down to enable background spelling.
Under 'help' and 'check for updates' if there is an update available it will take you to a page that describes how to set up updates:
https://www.freeoffice.com/en/tips-and-tricks-linux
Just scroll down the page a bit. After you set it up once it should continue to update.
Hope those help.
You will need to install YAD available from the repos. 
The popup code (dialog) and images (so you can see what you're getting) are here (the third example):
