Evernote deleted an important text

Hi,

I am an Evernote user since 2012.

Today I copied and pasted an important text between two notes. All worked fine but now I can't find the text probably due to a new bug: for me is a terrible problem because it was a work of four months and I need to recover it as fast as possible.

How can I resolve?

I am using Evernote 6.16 on Windows 10 (64 bit). 

Thanks for attention and best regards.
