First, check to ensure that you have enough space on the F: drive where you have your Sierra Chart installed. We wonder if the SierraChartStudies.dll file got corrupted due to not enough space on the drive. If you have enough space, then you will need to update to the latest release. You are running a very old version and you need to update. Follow these instructions to update: Software Download: Fast Update If you continue to have an issue with that file, even after updating, then make sure that your Virus Scanning software is not removing it. You should put in an exception for the entire Sierra Chart folder in your virus scanning software to ensure that it does not remove something it should not be.
