It is critical to note that "Authentication Code Update" in a security context refers to patching the software to accept new activation keys. However, for version 9.0c, no new security patches are being developed. The software functions exactly as it did in 2007. There are no new "authentication codes" being generated algorithmically by the vendor for general use; all codes are now issued on a case-by-case support basis.
Since Sony’s servers are dead, you have three legal options to get Sound Forge 9.0c running. Safe download sources:

The 9.0c update was a stability and compatibility patch released during the software's active lifecycle. It introduced support for new file formats and resolved various bugs present in the initial 9.0 release.
