On rare occasions, PC users will continue to experience problems launching ROES even after emptying the cache. Try a complete uninstall and relaunch of Java to restore your Java settings.
If you are a Mac user, do not uninstall Java.
To uninstall and relaunch Java on your PC: Go to the Java Download
page and download the Windows Offline Installation to your desktop.
Go to Start > Settings > Control Panel
. Double-click on Add or Remove Programs. Delete any program that says “Java, J2SE” in the description.
If
you have previously had a successful ROES launch, find the .whcc and
the .roescache folders in C:\Documents and Settings\[user name]\, where
[user name] is the name you use to log in and delete them both. Restart
your computer.
Install Java by double-clicking the file you downloaded
from the Windows Offline Installation page. When prompted, choose the
Typical installation.
After installation is complete, restart your
computer.
Finally, go to the ROES launch page and launch ROES.
