When the file names contain a period (dot) the export to EIP fails. CaptureOne 11.0.1. Mac version confirms that the file has been exported but in reality nothing was exported. I guess this is the same error we already saw when shooting tethered and files would not import when the filename contains a period.
I have to manually rename my files in C1 before exporting to EIP.
Please correct this bug in the next release.
Thanks
