function.unlink Problem after runing sitemap generator.

Code:

Warning: unlink(/home/user/public_html/vbseo_sitemap/data/progress.dat) [function.unlink]: No such file or directory in /home/user/public_html/vbseo_sitemap/vbseo_sitemap_functions.php on line 1074

I'm getting that error after Running Sitemap Generator. I checked the data folder to see if there was any progress.dat, but there wasn't.

I'm clueless, I have searched everywhere before posting here. If someone has any idea why is this happening plz help me

by the way, I have my data folder permissions to 777.

unlink() is a function that removes a file from a directory.

the progress.dat file is what generates the 'run log' when the sitemap generoatr runs (if you run it manually, its the output you see to your screen with number of sitemaps, processing time, etc)

If its already gone, perhaps it tried to run twice?

re-run the sitemap generoator again manually and see if you can reproduce it.

if it only happened this one time i would simply pass it off as a glitch
