find and edit this file: C:/programm files/EWA net/config/um_cfg.xml
Find this line:

And in this line:
change 480 to -1 .
If the solution does not work,Please try:
Delete the EPC application from Java in Control Panel.
2. Run the fix.
3. From EWA Admin Tool —> Restart EWA server service —> Stop EWA database —> Start EWA database. (Or you can simply restart your computer).
4. From EWA net shotcut —> Make sure that you have a valid key —> Log on and Start EPC.
5. Close EPC and EWA net (Internet Browser).
6. Create EPC shortcut from Java in Control Panel.
After this make new EPC&WIS shortcut (from JAVA) and this shortcut will never expire.
