[Closed] Bigfoot email forwarding problem - what does Servlet Exception mean??

Help... As bigfoot's email fowarding has stopped working 5 days ago, I wanted to log in and cancel my acccount, but when I try, it goes to a page displaying a lot of error coding.

Anyone know if this is "terminal"? (Needless to say, bigfoot do not respond to email or phonecalls)

Excerpt of code on page:
ServletException

CAUSE = javax.servlet.ServletException
at org.apache.struts.action.RequestProcessorprocessException(RequestProcessor.java:545)
at org.apache.struts.action.RequestProcessorprocessActionPerform(RequestProcessor.java:486)
at org.apache.struts.action.RequestProcessorprocess(RequestProcessor.java:274)
at org.apache.struts.action.ActionServletprocess(ActionServlet.java:1482)
at com.bigfoot.ef.strutsext.BaseActionServletprocess(null:-1)

PS I do realise the website probably has cat AIDS 😛
