This is probably a stupid question but here it goes- I got my new user license disk from DBA and also an update disk to 2004.1 version-  this is the first update I have gotten from DBA since joining IS Tech and I just wanted to know if I install the DBA update will it mess with my IS Tech updates or do I need to reinstall the latest IST update after the DBA update? or just install the DBA update on get working? or not and just do the license update.

Thank you very much-  will do just the license

Yes, if you install the DBA CD, you will erase all the IS Tech programs and replace them with the original standard DBA versions.  Not a big deal, you just need to reinstall the latest full update from IS Tech.
