I don't get it. Why am I getting this error? Is it a security thing?

you probably compiled your jars for a higher version of java then its trying to run on. for example your applet is compiled for java 1.6 and your trying to run it on java 1.4.

That's very odd, since the only version of both the JDK and the JRE that I'm running is 1.6.0u13. Is it perhaps on the server side (I wouldn't think so)?

hmm, some googling of the issue reveals this thread http://forums.sun.com/thread.jspa?threadID=640927 maybe it'll help.

Thanks for your suggestion. Progress: now I'm getting the following error (with a misspelled "please"):
"An error occurred while loading the applet.
Please contact support to resolve this issue.
Fatal error occurred (5): Corrupted pack file: magic/ver = 3C68746D/62.108 should be CAFED00D/150.7 OR CAFED00D/160.1"
