please help!!!

No STP file was uploaded.

I just opened this one

StepFile.stp (9.7 KB)

please verify the import/export is loaded in the File>Properties>Plugins> search by STEP

Thank You Thank you Thank you, this was the remedy to my problem but how did this happen spontaneously and how do I prevent this from happening in the future?

Perhaps something to do with the plugin install/load?
