Why doesn't csvread work?

In my cd X:\TMMV17\Post I have a text file by name "Wall_fric_1212.txt". I have previously been able to run a csvread as follows:
csvread('Wall_fric_1212.txt',5)
However csvread has suddenly started to output the following:
"Error using csvread (line 34) File not found."
I have tried "rehash path", "rehash" and "addpath 'X:\TMMV17\Post'". I have tried
csvread('X:\TMMV17\Post\Wall_fric_1212.txt',5)
I have also tried renaming files, moving files etc. No luck. If I run
which('Wall_fric_1212.txt')
X:\TMMV17\Post\Wall_fric_1212.txt.
What could the problem be? Thank you in advance for your help. Regards Lindblom Markus

Note that playing around with matlab path (using rehash, or addpath, or ...) is not going to help in any way with your problem. The matlab path only help matlabs finding m files, not text files which need to be either in the current directory (change with cd) or referred by their full path.
It looks like your X: drive is a mapping to a network folder. Possibly, the mapping (done by the OS, nothing to do with matlab) has been lost. In any case, you can use the UNC to refer to your file, so:
csvread('\\ad.liu.se\home\marli379\TMMV17\Post\Wall_fric_1212.txt', 5)

Use absolute file names in every case:
csvread('X:\TMMV17\Post\Wall_fric_1212.txt', 5)
callbacks of GUIs oder TIMERs can change the current folder during the processing, so never rely on relative path names.
