My guess is the two problem are unrelated. The client problem probably has to 
do with registry entries not matching the data in the config for the 
SourceJammer executable. The sourcejammer.properties file contains a reference 
to JRE version. This value must match one of the values under 
\HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment

The server issue sounds like it's probably unrelated to the new JRE. My guess 
is you got into some kind of race condition on the top-level folder when you 
restarted the server, and two threads tried to lock it at the same time. This 
happens from time to time when someone says "OK, I restarted it. Try it now!" 
and several people try to log in all together. Try restarting the SJ server and 
see if that fixes it. (I know, the lame old M$ solution to every problem, but 
it often works!)

Let me know if you're still having trouble.

Subject: Re: [SourceJammer-users] JDK 1.6 Issue

I'm having a similar issue with the client. 1.4.x on Windows works fine. 
But if I update the JRE to the current version, SourceJammer stops 
working. It claims that I need a newer version of Java.
