I have a full version of TINA SPICE, and I need to consider an upgrade. However, I cannot access Tina's website. typing www(dot)tina(dot)com yields no results. Neither does DesignSoft(dot)com. Has TI acquired all rights to Tina SPICE, or is my computer just not able (?) to access their website? Presently, what are the differences between the TI version and the Full Industrial version I have?
