Did you get cables for laptop from them too or you bought it separatelly ?
I downloaded their evaluation version but I don't have cables from my OBD to PC serial connector.
Actron'* cables don't fit.
I saw one site,but they want $80. Just plain rip-off.
There was one person here on BC who was making these cables,but I didn't get answer on my PM to him.
Regarding your canister purge I don't remember for sure ,but I think when I scanned my car purge was on too when car was running.
Thanks in advance for info.
EDIT: This is from FSM:
The PCM pulses "ON " the solenoid to allow purge when :
1. The engine is fully warm.
2. The engine has been running a specified amount of time.
3. The IAT reading is above 50 degree F.
