Hi Peter,
Sounds like you are using the TS API from CVI. There is no update to the TestStand API help. You will need to figure out the exact property you are trying to obtain and then refer to the TestStand programmer help file for specifics on the actual property you are trying to get. For example, if you are trying to access the Id property of the Sequence File then under the TestStand Programmer Help file you can search for "Id" to find out the specifics on that property.
