Unsupported comm operation exception????

[greypride]

hello, please can someone help me solve my problem

ive installed the all the java files and megajolt on my laptop but when i start up the configurator i get this:

javax/comm/UnsupportedCommOperationException

java.lang.NoClassDefFoundError: javax/comm/UnsupportedCommOperationException
at org.megaJoltLiteJr.presentation.MegaJoltLiteJr.getIgnitionController(MegaJoltLiteJr.java:67)
at org.megaJoltLiteJr.presentation.MegaJoltLiteJr.readConfiguration(MegaJoltLiteJr.java:715)
at org.megaJoltLiteJr.presentation.MegaJoltLiteJr.reloadConfiguration(MegaJoltLiteJr.java:215)
at org.megaJoltLiteJr.presentation.MegaJoltLiteJr.<init>(MegaJoltLiteJr.java:61)
at org.megaJoltLiteJr.presentation.MegaJoltLiteJr.main(MegaJoltLiteJr.java:631)

if i click ok it then opens the configurator

what does this mean?

previously ive installed it all on my pc and had no problems

thanks
