Update butons not working

I have installed flexicontent on my joomla 1.5.22 and all was OK, but when I wanted to click on the red Update buttons (those on the right side) I cant, I click and nothing happens, i wanted to Import Joomla Structure, after I have clicked on the button, a strange page have opened (no joomla structures around, just the warning message and the buttons), i have tried to click on the buttons on that page, but nothing happened.

What's the problem?

I want to modify the component to display articles from different section, correlated with the visitors town. (geo-targeting)

Later edit:
Firebugs give me this error when loading page:
SqueezeBox is not defined
SqueezeBox.initialize({});

could this be the problem? does flexicontent depends on this? could you advise me how to repair the problem?

hello
do you desactived plugin for mootools
joomla cache and gzip compression ?
regards

Gzip and cache is off problem is still there.
Cache cleaned, deactivated CssJsCompres plugin.

What do you mean by: do you desactived plugin for mootools?

All other buttons in my website back-end are working.

i have noticed that after I click on the button, the link changes from:

www.aaaaaa.ro/administrator/inde ... exicontent

to ('#' at the end)

www.aaaaaa.ro/administrator/inde ... xicontent#

if you want i can give you access in the back-end of the website as a super administrator to investigate the problem.

in plugin administation search plugin for mootools compatibility and desactived
clean cache and expired cache
deconnection / reconnection and try your button
regards

I have searched, and i do not have any plugin for that...
I have flowed all your advices
