I am sorry to hear about your data loss.
Regarding the paging, there is unfortunately nothing else we can recommend. I personally just tested it on a demo site (with and without ajax) with no problem. I then repeated the same test on a client’s custom site with the same result. I would recommend product support; However, our developers would end up doing the exact same steps that were recommended here. We have not received any other complains regarding this issue.
For the category section, I checked your website and its working fine. We try to use as little css as possible (except “all in one” shortcodes), for many reasons. I will recommend to the development team, that they consider adding some css for situations like yours. I can see another release scheduled within 48 hours. A fix may be in that release.
