It appears you have selected the "Netwrok" option when installing TransMagic. However, for the eva;uation you would need to select the default "Node-Lock" (Stand-Alone) version. You can correct this in the following two ways:
1.) If you are comfortable editing the registry you can navigate to this value in the registry:
Then change the "Network" value from "true" to "false."
2.) Unistall TransMagic R8 and re-install it - this time selecting the default "Node-Lock" (Stand-Alone) option.
Then after correcting this, when you start TransMagic, you will be asked to submit youre "Reference Code" on-line and you will be emailted you License Key. Then, you should be all set to go.
