Thread:Project:Support desk/Problems importing

I managed to get MediaWiki working earlier this morning and everything appears to working fine but I'm having problems trying to import files. These are the errors I'm constantly getting:

Warning: XMLReader::open [xmlreader.open]: Unable to open source data in /www/zxq.net/h/e/l/helsinkipedia/htdocs/wiki/includes/Import.php on line 53

Warning: XMLReader::read [xmlreader.read]: Load Data before trying to read in /www/zxq.net/h/e/l/helsinkipedia/htdocs/wiki/includes/Import.php on line 399

I've searched online and through the manual for hours and I can't seem to find a solution to this. The page itself also seem to display properly (the error message kind of sits in the background messing up the layout a bit) and another error pops up saying the upload failed but the wording is incomplete (Import failed: Expected tag, got). Is there something wrong with Import.php or the XML file itself? I'm running MediaWiki 1.19.2 on the web host Zymic.com who uses the most recent version of PHP. The backup was done by me through Special:Export on Wikkii if that helps any. I'm new to managing MediaWiki software so I apologize if my question seems silly.
