I use Tex Live and TexWorks/Kile on Windows 7. I have biber 2.10 and biblatex 3.10 fully updated (that is what Tex Live Manager 2017 says).

But I can't compile a file created with another latex system as I get the error message:

Package biblatex Warning: File 'filename.bbl' is wrong format version - expected 2.9.

When I check the file filename.bbl it starts with

% $ biblatex auxiliary file $
% $ biblatex bbl format version 2.8 $
% Do not modify the above lines!
%
% This is an auxiliary file used by the 'biblatex' package.
% This file may safely be deleted. It will be recreated as
% required.
%

so the file has the version 2.8. This file was created with another latex system. I would like to make it run on my computer :) What can I do?

    As the beginning lines of the .bbl file already tell you, you can simply delete the .bbl file and then recompile the .tex file on your system.

To successfully compile your document, you can sefely delete the .bbl file that was created on a different computer with a different version of biber. If you then recompile the .tex file on your system (using latex, biber, latex, latex), the required .bbl file will be created by biber automatically.
