I am having a problem opening a client I need to run with Java. When I try to open the file(.en.jar) it starts off "Java opening..." but then a window pops up saying "Application Error-Unable to launch the application". Then when I click on details it says the following...

CouldNotLoadArgumentException[ Could not load file/URL specified: C:\DOCUME~1\ADMINI~1\USTAWI~1\Temp\javaws16]
at com.sun.javaws.Main.launchApp(Unknown Source)
at com.sun.javaws.Main.continueInSecureThread(Unknown Source)
at com.sun.javaws.Main$1.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)

java.io.IOException: File too large

at com.sun.javaws.Main.continueInSecureThread(Unknown Source)
at com.sun.javaws.Main$1.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)


Please can someone help me with this as I must be able to run this client. Forgive me if this is posted in the wrong place.

Thanks in advance.
