I bought a USB MultiCard Reader to enable me to upload photos from an SD card. When I connect it to the PC it says it does't recognise the device. I also get an error loading message 'CTMBHA.DLL 'A dynamic link library (DLL) initialization routine failed'. This msg comes up all the time and I just ignore it. Could the two issues be related? Forgive me in advance if I am doing anything stupid as I am a complete technophobe
