The TruePak 1 for Targa 2000 release 2.1 lets you use the display card with After Effects in Windows NT when Service Pack 2 or 3 is installed. If you have the AVID MCXpress, which uses a Targa 2000 graphics display card, After Effects returns a system error during startup. To avoid the system error and disappearing windows, AVID and Truevision recommend using the Targa display card as a secondary display card. Make sure you're using the latest drivers for your graphic display card. To obtain the latest drivers, contact the manufacturer.
Many drivers are available to download from the manufacturer's Web site.
To be able to open a project transferred via a removable drive from After Effects 3.1 for Windows to After Effects 3.1 for the Macintosh, you must assign files with an .aep extension to After Effects using the PC Exchange control panel. PC Exchange is included with System 7.5 and later. Adobe does not support this procedure. As, then select a file in a supported file format. Source footage in an unsupported file type cannot be relinked and remains listed as missing.
