[TYPO3] mm_forum: New Topic and Reply links dissapeared. Help!

[Cray Flatline]

I have installed mm_forum 1.7 and set it up. After creating categories
and forums, i open page inside forum and try to press button New Topic
but it doesn't work. As I see, where is no link

<div class="tx-mmforum-pi1-listtopic-newtopic">
   <div class="tx-mmforum-textbutton">
      <img height="16" width="16" title="" alt=""
src="typo3temp/GB/d9e245e717.gif"/>
      <span class="tx-mmforum-buttontext">Новая тема</span>
   </div>
</div>

I thought that it's permissions problem, but even when i give user admin
rights - no link. ): But, for example, same buttons works on the PM
page. Really strange.

Can anybody help me or even give direction to solve this problem?

Thanks a lot.
