Hi, I'm new to this, not sure if I've put this query in the right place or not - it's all a bit hit and miss but I'm getting a bit desperate!

I recently bought a Nokia 62301 and installed the Nokia PC Suite, also Bluetooth Mini Dongle and installed the BlueSoleil. All OK until I decided I wanted to have a go at downloading mp3 music tracks. Being new to all this, it took me ages so I was not very happy to get a message saying I didn't have enough memory. The book that came with the phone mentions "listening to your favourite tracks" though it didn't say exactly how many!. There were two Tears for Fears tracks already on it which have now been deleted to make more room. I have only 4 music tracks on my phone. I bought a new 512mb MMC card and was keen to get downloading. Again I'm told I don't have enough memory. The Nokia PC Suite is not recognising my 512 card but is still 'reading' my old 32mb card. I have looked at some of the other messages and people seem to have successfully transferred music files/play lists. How have you done this when I don't seem to be able to and why is the PC suite not recognising the new card?  It's all a bit disappointing. Can someone help me out here please, and give me some very simple, easy to understand instructions as to what I need to do here.Thanks.
