It sounds like that specific file is corrupted for some reason. This is very odd, but here is what we want you to do, which should fix it:
- Exit from Sierra Chart
- Using the Operating System file manager (File Explorer in Windows) go to the Sierra Chart installation folder (typically C:\SierraChart)
- Go into the "Data" folder under the Sierra Chart installation folder (such as C:\SierraChart\Data)
- Delete the file named "USDCHF.scid".
- Start Sierra Chart

The chart will automatically redownload the data for that chart, and you should be fine. If you continue to have an issue, let us know.
