Hi folks, I am re-running some ITSA script from a couple of months ago with some updated data and have encountered this error:

Code:
tsset surgery_date_month, monthly

itsa countrecord_id, trperiod(722) lag(1) posttrend figure

actest, lags(12)
struct ms_vcvorthog undefined
(118 lines skipped)
(error occurred while loading actest.ado)
The only thing that has changed from a couple of months ago is that I have added more data points, so I am unsure why this error is occurring. I have tried uninstalling and installing -actest- but that did not work.

Any help would be greatly appreciated.
