invalid LOC header (bad signature)

[ACDC]

I am getting this error after trying to log in via the browser into my test system. (V3) - This happened after I successfully ran the Test option in the configurator - Any Ideas ? This is strange as I have gone through numerous test versions and then all of a sudden out of the blue?

javax.servlet.ServletException: jzentry == 0,
jzfile = 47874040,
total = 129,
name = C:\AwareIM\Tomcat\shared\lib\wsdl4j.jar,
i = 66,
message = invalid LOC header (bad signature)

Looks like disk corruption to me. You may need to check your disk and re-install Aware IM if necessary
