Apologies if this is answered elsewhere, but I've been searching message boards for hours and tinkering with fixes... it seems to me that I have a problem with my MiKTeX / TexMakerX installation.

I have just installed the most recent installation of MiKTeX (64bit version) and biblatex, and manually placed the most recent biber.exe in the MiKTeX /bin folder.

My bibtex command is set in TexMakerX as

"C:/Program Files/MiKTeX 2.9/miktex/bin/biber.exe" %

And my "quick build" function is set to pdflatex - bibtex - pdflatex - pdflatex.

I've been testing with the biblatex samples (I'll just call it sample.tex, with biblatex-examples.bib downloaded in the same folder) from http://www.ctan.org/tex-archive/macros/latex/contrib/biblatex/doc/examples

Invoking pdflatex THEN bibtex generates the following errors

warning - no file sample.aux
warning - no file sample.bbl
--a whole bunch of undefined citation errors--
warning - empty bibliography on input line 51 %whereever \printbibliography is placed
warning - file 'sample.out' has changed
warning - there were undefined references
please (re)run Biber on the file:(biblatex) sample(biblatex) and rerun LaTeX afterwards

Running biber as requested through a command window generates:

data source ....(long path out of Temp folder)...\inc\lib/Biber/LaTeX/recode_data.xml not found.
Compilation failed in require at Biber/Utils.pm line 20.
BEGIN failed--compilation aborted at Biber/Uutils.pm line 20.
Compilation failed in require at Biber/Utils.pm line 8.

BEGIN failed--compilation abobrted at Biber.pm line 5.
Compilation failed in require at script.biber-MSWIN line 17.
BEGIN failed--compilation aborted at script.biber-MSWIN line 17.

So... there seems to be no communication between the local .bib file and the latex/biblatex system. And I'm clueless on what to do after all this tinkering...

    Welcome to TeX.SX! Your problem has already been addressed: remove the directory related to biber in the Temp folder. See tex.stackexchange.com/a/54545/4427 – egreg Sep 17 '12 at 21:52

    Do you have backend=bibtex as an option of biblatex when you use bibtex? – Guido Sep 17 '12 at 21:53

    It looks like you need to delete your biber cache and re-run it. On the command-line run biber --cache and delete the folder it reports. – PLK Sep 18 '12 at 3:44
