System Extension Cannot be used ??

[streetbeats]

Just installed 4.0

Everything has always worked perfectly with my G5 and UAD until now..

Upon reboot I get this error message appear:

System extension cannot be used

The system extension “/System/Library/Extensions/UADDriver.kext/Contents/PlugIns/UADEngine.kext“ was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.

Clicking 'OK' then pops up this one:

System extension cannot be used

The system extension “/System/Library/Extensions/UADDriver.kext“ was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.

G5 DP 1.8 revB
2Gb RAM
10.4.2
2xUAD-1
DIGI 002R

Any ideas ?

Re-installing didnt work :/

Turned out to be a corrupt download - redownloading and installing again fixed the issue...

beware - a corrupt d/l might still work and appear normal...
