Hi... There's a chance that your new installation of Aware has put java 32 over the top of your 64 bit version.
Did you take a back of the java 64 JDK folder in the Aware folder? Possibly you have memory settings higher than java 32 bit can handle. (1GB Max)
If this is the case, then your solutions are to put your previous (64 bit) JDK over the top of the new one that has come with the new installation or alternatively you can adjust the memory settings outside of the GUI by changing them in AwareIM/bin/startAwareIM.bat
