Lightning struck my system and one inverted was damaged beyond repair.

I obtained a new one from Mustek.  They promised to ensure that the new one will have the same version of software on it as my other two (71.70).  

However, after my installer put the new one back in it does not communicate with the other two.  It's software version number is 71.80

They said that they will send me the software but I am looking for a description of the steps one takes to upgrade the software.

Thanks

I found posts by Coulomb with references to the Australian web site.  I should be fine now.
