I dont know if PC radios' software can be tweaked for region or not. But I am pretty sure the actual stations frequencies differ in Europe than in North America. Something like odd numbered frequencies here (like 99.9Mhz, or 87.5Mhz) whereas in Europe it is even (like 99.8Mhz or 87.6Mhz). I cant remember if this is true or not. But you would know

Just something you should be aware of if the problem exists. If the tuner can go in 100Khz jumps or something, then you should be safe.
