Bc2000 (for the BCF2000 & BCR2000)

hi, first i've searched on this forum but found no responses, i'm not familliar with yahoo groups and it's very hard to find information since i find it totally not ergonomic. also i'm not english so it makes it hard to me for founding something.

so i bought a bcr from ebay months ago and i noticed that some rotaries doesn't works well maybe i should have returned it but it was a great deal for me, 80 euros.
I got BC Manager and changed the resolution of all rotaries because I thought they were too slow.
