Accordion – Import 3rd party

Hi. I started an import under 3rd party importfrom Ultimate FAQ which had 15 \"questions\". Now the import won\'t stop. After 1 hour I had 503 imported FAQs. I have tried to deactivate both plugins and reinstall them. I have even had both plugins deactivated and uninstalled for a week and just installed Accordion Again and even now it says importing and keep on processing. I have not installed Ultimate FAQ again so it doesn\'t collect any data but probably use a lot of workload on my website.  What can I do?
