I decided to renew my subscription, though I am using ver 4 instead of reinstalling 5. Version 4 works okay and I have other tools running (MBAM and SAS). I also make sure to shut down before I remove any USB hard drive. Then I make sure to reconnect that USB hard drive before I start up the computer. This is with XP SP3. -- It is easier for a camel to put on a bikini than an old man to thread a needle.
