Updating from 8.01 to 8.03 has blown this system up (ProTools LE)
Using the 32-bit emulation structure has not been a problem - LE v8 works a treat (for this newbie). After the update, a message appears requesting InterLok driver update (go to paceac.com; etc.). The EXE is downloaded & run, but an error gets thrown (error1326.Error C:\windows\system32\Drivers\tpkd.sys GetLastError:2).
Then clicking on the ProTools app icon yields an immediate boink . . .
Then I uninstall, re-install v8.00 & everthing is fine (can't re-install 8.01 though - it used to be possible). Spreads across two (2) monitors fine, yada, yada . . . And I get the "Update Available" message just fine, too . . .
What's up? Apparently InterLok is an anti-piracy method - seems silly, doesn't it? How is an "Update Available" message received but the "Update" doesn't have the capability to create permissions?
Any thoughts out there?
Firewall (Zone Alarm) is turned off during every install; even went back to v7.4 in my re-install progression . . .
Thanks in advance for any help!
