With the latest releases of Sierra Chart there are changes to ACSIL that require a recompile of the studies.

If you get your studies from a third party, then you will need to contact them regarding getting you updated versions of the studies.

All of the information related to these changes is in this thread:
Upcoming Development and Internal Number Precision Improvement Project

You can go back to the previous release you were on by selecting "Help >> Install Previous Version".
