Alloy code completion not working

Hello,

I have just switched from developing using classic mode to alloy. my problem is that when i try to create a button for example, i dont get the options available after i type < in the index xml file.

<Alloy>
    <Window class="main">
        <
 
    </Window>
</Alloy>

I have tried to do the same thing on my friends computer and it works fine. he gets all the available options such as Button, ImageView etc.

I really need this working as its very hard for me to work with it.

Regards
