You provided a link to your Wordpress blog, so do we assume you were using Wordpress itself, or some Word Processor installed on your computer?
If you were using Wordpress, try a test. Create a new blog, different name to the one you have lost, then save it. Watch the process carefully to see how and where it is saved. Use that information to search for the one you lost.
The same with any word processor.
I note you said (in the blog), that automatic backups were done. How is this done and where does it save the backups?
On the 17th may i finally started writing a fiction piece using my wordpress blog, didn't titled it but did save it. it was also autosaved a few times.
When i went back into it yesterday it was gone, i've gone through all the i was told to when i contacted support (link below) but nothing worked.
Is there any software out there that's either free or not to expensive that can reclaim the lost writing piece?
