This error is linked to the install of FactoryCast 3.01 on a PC which has Concept 2.6 SR1 installed. FactoryCast 3.01 will overwrite the current AI.DLL file in Concept 2.6 SR1. You will not be able to open a project and will get the error message, "Call to Undefined Dynalink".. In order to work around this you should copy the AI.DLL file from the Concept install CD back into the Concept directory on your PC. This will bring the AI.DLL file back up to the most current version. The future release of FactoryCast basic will address this issue.
