Drop all these files into C://Cavedog/Totala or C://Cavedog/Totala TABA.  
Then make sure you do not have any 3rd party units AND be sure that you 
do not have the extra 6 cavedog units that were released after the 3.1
patch.

P.S. If the Arm and Core SAMs don't fire, you forgot to do that last step.


How To Upgrade Stuff:
Build upgrade 1.  You have the first upgrade, increasing the power of your
unit.  Now build upgrade 2.  You, again, have increased the power of your
unit.  Keep in mind upgrades affect all factories of the same type.  Also,
you can research upgrade 1 in one factory and upgrade 2 in another and as
long as they're the same type, all units from those factories will be upgraded.

How to build T3 Units:
Make sure upgrade 2 has been researched for a certain factory.
Build an Experimental Units Gantry.  Build
the corresponding unit for the upgrade you researched (laser upgrade -> 
experimental laser kbot - Krogoth).
