Hi,
Seems import/export-related C routines are corrupted. Please try the following:
1) Close Origin, and navigate to the Origin program directory.
To know the path, you can type the following command in the Script window
(followed by pressing ENTER key):
system.path.program$=
2) Delete whole "OCTemp" subfolder, and restart Origin.
Hope this works.
