# Biber/BibLaTaX problem: no such file or directory in cache [duplicate]

I am having a problem using biber/biblatex, that I just can't seem to solve. The first problem was Biber complaining about finding the wrong version of biblatex control file (2.6 instead of 2.5), which I tried to fix by installing the latest biber (1.9) as suggested here.

Now however, the following error occurs:

- sysopen: No such file or directory at  C:\Users\usermane\AppData\Local\Temp\par-7363686d6964746b\cache-c38a9b05b97a81d339b4947ba00f0aacefe00497\inc\lib/Biber/LaTeX/Recode.pm line 112.

INFO - This is Biber 1.9 INFO - Logfile is 'test.blg'

What to do?? Is it the same problem as this??
