I could see all the captions. so what could be wrong?
This might suggest that your gallery itself is OK and that your browser may be displaying a cached version of your 'gallery.xml' file (without the captions).
If you are sure that your browser cache has been completely deleted, you can also try the following.
Go to your http://www.thelacunasofgrace.com/2011/gallery.xml page directly in a browser, refresh the page (press F5) and then go back to reload and view the gallery.
The link to upgrading galleries to 2.1.3 does not work.
Sorry. I have now edited the post and corrected the link.
I could pass you a sample of my gallery folder for you to take a look.
Your gallery (including captions) displays fine in all browsers on my PC.
By all means email me your gallery folder (you can find my email address in my forum profile) but I have already taken a look at your embedding code and I have used your SWF and XML files in test galleries and, no matter what I do, I cannot find a problem or replicate your scenario.
However, I would still recommend upgrading to SimpleViewer Standard v2.1.3.
