Symptom: Inventory in Magento Admin displays "0", but Searchanise Instant Search Widget displays "In Stock"

I suspect it is a conflict with an extension I have running, from here:

• https://www.magentocommerce.com/magento-connect/product-attachments-extension.html 
  

About 8 months ago I reported a problem with search not working after I updated to version 3.1.4 and your developer was able to fix it. I believe your developer fixed the problem by deleting the virtual product I had created:

• https://help.searchanise.com/support/discussions/topics/11000008746 
  

However, I did not realize at the time that the product attachment page stopped working:

• https://www.ateprotools.com/download-user-manuals.html/ 
  

I fixed the virtual product page recently, but now Searchanise is not updating anymore. So I suspect these problems are related. I would appreciate some help on getting both to work. Thanks in advance.

Here are the relevant details:

I created a virtual product page to list all product attachments :

• SKU user-manuals 
• Product ID 2445 

It has a Custom Layout Update:

<reference name="product.info">
      <action method="setTemplate"><template>catalog/product/view-manuals.phtml</template></action>
 </reference>

I am running: 

• Magento ver. 1.7.0.2 
• Searchanise 3.1.4 
• Uni_Fileuploader 0.2.1 

FYI, they were both working with Searchanise 3.0. So something changed in the new version to cause a conflict.
