Interesting. I have used Extreme Call Blocker for three years on maybe 7or 8 different phones and never had that happen. I never pay any attention to. *where* it installs...I let it do it's thing in that respect...so maybe there is where your problem arose. It may not like being moved from your SD card to the main phone. I don't know, I'm not a technician.
