Query: money wasted

I bought a cp9145 to work on my 95 Caprice (which is an OBD1 car) and using it has been a very frustating experience. Including the adapter cord for obd1 cars, I paid about $230 (not from Amazon), and so far, the information it has given me has been worth about 37 cents to me. The check engine light was on and the scanner told me "dtc 26 Output driver module fault CCP circuit". I found out, by other means, that the problem was an electically operated valve in the Evaporative Emissions Control system. Actron does not provide any other information for OBD1 cars and did not respond to my e-mail questions. I find the manual poorly organized and difficult to use. Also, the outside of the box it came in says it has a one year warranty, but when I got it home, there was no warranty information inside the box. I have not had any trouble from my OBD2 car, so I cannot comment on that function.
