After upgrading the computer import function
Upgrading from DS 6.9 SP1 MP1 to DS 6.9 SP2 apparently breaks the Import Computers function.
Everything seems to work but at the end you get the following message:"An unhandled win32 exception occurred in Express.exe" and the DS console shuts down without importing the computers.
A workaround for this issue has been found by "Stefan Cleuren"
Step 1: File > New Computer
Step 2: Now you get the option of importing once more
Step 3 : Select your import file
Step : Done !
