Archive administration

[apkoutsou]

I have put some articles to archive and published to archive module, but even though the month is shown inside the module, when I click on it elxis returns a message that say no article was found for that month...

What am I doing wrong 

Edit: I almost forgot; I'm running Elxis 2009

Well this problem has come up to me again... I did a thorough search in the forum, but no answer though many similar posts...

Do we have a solution for this one?
