study which was stable for months now unusable. need to fix it before tomorrow open.

- installed latest
- recompiled study - no errors
- opened chart studies - the existing study in it shows (unknown name) and no parameters or subgraphs in the study settings
- removed
- added again - in the Add Custom Study - the dll name and the study name shows correctly, but when added - it is same as above - (unknown name) etc

I asked a month ago what do i need to do to make studies compatible - you said - nothing, just recompile.

moreover - i used Install Previous Version - it is now 2947.58042 - same result.

I need this study - it is important part - i cant trade without it.

Only change I did in the code is commented out sc.FreeDLL = 0 that now does not compile (seems you removed FreeDLL)

please advise

I have seen this behavior from time to time. Not sure what causes it. Try rebuilding again. That has worked for me.

If you add another study, do the Inputs and Subgraphs show properly in the settings window for that study?

If not, then this is a resources issue with your computer. Reboot your computer and then try to run Sierra Chart without any other programs and see if you continue to have an issue.

Also, when you downgraded to 2947, did you recompile again for that version? You would not be able to use the .dll that you had created in 2973.
