Language-files

Hello, I use the free Catch Box-theme and have started to make a swedish translation. When I updated from 1.6.2 to 1.6.3 some of my translations stopped working, but some still work and I can't find any obvious reason in my files. For example the translation of <span class=\"sep\">Posted on </span><a href=\"%1$s\" title=\"%2$s\" rel=\"bookmark\"><time class=\"entry-date\" datetime=\"%3$s\" pubdate>%4$s</time></a><span class=\"by-author\"> <span class=\"sep\"> by </span> <span class=\"author vcard\"><a class=\"url fn n\" href=\"%5$s\" title=\"%6$s\" rel=\"author\">%7$s</a></span></span> doesn't work anymore but <span class=\"%1$s\">Posted in</span> %2$s still does. I've tried to make a new translation from the included .pot-file but the result is the same /Regards Johnny
