I try to open a .stp file and I get a message "the default templates are not valid. The problems can be resolved by correcting the default templates under the options dialog.
Do you want to contunue with a blank template". If I click CANCEL it wants to use a ASSEMBLY template instead of the PART template.
Do you have the default templates in the default location? (not renamed or custom path?)
Can you zip and attach the *.stp file here?
the step file may be an assembly.
