latex to png not working

Hello. I'm trying to export an Org file with some basic latex code (block
with "#+BEGIN_SRC latex :file block1.png" and "tex:dvipng" in "#+OPTIONS:")
but this shows up in the *Messages* buffer:

>org-babel-exp processing...
>executing Latex code block (block1)...
>Failed to create dvi file from
c:/DOCUME~1/User1/CONFIG~1/Temp/orgtex1376-zt.tex
>Code block evaluation complete.
>Formatting LaTeX using dvipng

The ODT document is created but, obviously, without the PNG formulas. It
happens too with inline LaTeX fragments:

>Creating LaTeX Image 1...
>Failed to create dvi file from
c:/DOCUME~1/User1/CONFIG~1/Temp/orgtex124_dQ.tex

c:/DOCUME~1/User1/CONFIG~1/Temp/odt-124Zro/Images/0001.png

Org's LaTeX preview doesn't work either. The dvi files are not being
created.

My setup includes:
- Windows XP SP3
- Emacs 24.3.1 with Org 8.2.1 (20131007 from ELPA) and AUCTeX 11.87.1 (from
ELPA); everything correctly (and cleanly) installed
- TeX Live 2013 (full install), on Windows' PATH

Standalone dvipng works ok (tried it with a small dvi file through Windows
command line) and latex too (through cmd, Org---latex & pdf export--- and
AUCTeX).

Thanks for reading.

The problem went away once i changed the values for both TEMP and TMP
environment variables to "C:\Temp" (without quotation marks). This---i
think---has to do with long filenames (path to TEMP folder).

Great, great job by the way. Org makes so much things easier. Thank you
very much!
