annoying pop up message

[[email protected]]

Hi,
Every time I change a translation it gives me this Pop up message:

<br />
<b>Warning</b>: unlink(/home/timovorg/public_html/timofeev.net/plugins/system/gtranslate/cache/ru/cc535f81586e1ab7f6cbb17ff3a39046) [<a href='function.unlink'>function.unlink</a>]: No such file or directory in <b>/home/timovorg/public_html/timofeev.net/plugins/system/gtranslate.php</b> on line <b>166</b><br />
Success

Can this be fixed somehow?
thank you

Make sure that the cache folder has write (delete) permission.
