Ok, very very last option 
Do you get the “No interactive network license available” message when you try to start Softimage 2010 ? If not, then you need to edit setenv.bat and change the licensing method to Network:
set SILicMethod=Network
If you do get “No interactive network license available”, then that means Softimage cannot connect to the license server.
I get that no Activation notice - You have 29 days remaining to register and activate your Audodesk Softimage 2010. What would you like to do?
-Activate
-Run the product
I’ve tried to activate but it never recognises my serial no and if I select that I do have an activation I don’t know what to paste or copy from the license.
Can you still start 7.5?
I’m getting the same message as when starting 2010. Don’t know what I’ve done wrong.
This is what I get from the Perform Status Enquiry

I went through the videos yesterday
ADSKFLEX_LICENSE_FILE should point to your license server…
Just to be sure that would be C:\Program Files\Autodesk Network License Manager\SFTIM2010enlicense.lic
I’m going to go through it all again, here’s hoping.
