Creating csv file error

Hey there,
thanks for awesome plugin. However I′m getting this kind of an error when trying to make .csv file:
“Warning: fopen(/www/doc/www.datascript-elearning.cz/www/wp-content/plugins/lbak-user-tracking/csv/lbakut114rows030611090254.csv) [function.fopen]: failed to open stream: Permission denied in /www/doc/www.datascript-elearning.cz/www/wp-content/plugins/lbak-user-tracking/php_includes/main.php on line 163
Could not create .csv file. Please ensure that you have write permission on your server in the csv directory of this plugin.”
Guess thats because my website is uploaded in a directory /wwww/ at my website and other directories hosted there like /doc/ are read only (cant do pretty much anything with that…)From my point of view the fopen path should like “www.datascript-elearning.cz/www/wp-content/plugins/lbak-user-tracking/csv/lbakut114rows030611090254.csv” without “/www/doc/”. Is there any chance I can fix that by myself or could you make any upgrade?

Thanks in advance…
