Superlab will not run

I have unregistered 10 licences so that I can install elsewhere. This was successful.
I have remotely installed Superlab on 3 computers and on two of them when I run the program the egg timer comes up then stops but does not open the program.

When I try again I get the message that it is already runnning.

When I look in Task Manager it is running Superlab twice.

I have a print screen but it is too big to upload here.
I’m running Superlab 4.00 on Wnidows XP.

Any ideas?

Thanks

Try downloading SuperLab 4.5, which is our latest version of SuperLab. You can find the download here: http://community.cedrus.com/showthread.php?t=1131

Use your SuperLab 4.0 license number to start the activation.
