I fail to see the problem. The default index page for the site, which is the only one any normal visitor sees, is an index.php which does a 301 Permanently Moved Redirect to a site that has nothing to do with your x10hosting account.
This is in addition to the files contained in the candidatura/files which are likely the PDF and DOC files you're referring to. But did you juts say "online form where people put their CVs in PDF and DOC and uploaded them for evaluation to a job post?" Personal account holders are not permitted to resell, store or give away web-hosting services of their website to other parties. Web hosting services are defined as allowing a separate, third party to host content on the owner's web site.
My guess? That's what tripped the File Hosting suspension. This isn't a suspension we can undo at this point - having an index.php that redirects everyone away from the site was likely the start of it, but having other users uploading PDF's and DOC's sure didn't help.
