From ISTS download page--
Whenever you create or delete a company in DBA, the data dictionary files in Evolution need to be reconstructed. Download the file from this page http://www.istechsupport.com/datadict.asp and unzip to DBAMFG. Get all users out of DBA and/or Evolution. Then double click on the TAS6EVO.EXE in the DBAMFG folder (not your local icon). The program will load and a window will come up that says Create Code Base Dictionary. Click Next and allow it to run through all the files.
