CompuServe Messages

Hello, All. I have experience in using ZModem with FidoNet BBSses. No problems. I use NComm, and Compuserve has only XModem and Kermit in common with Ncomm. Both don't work, when I try to download something. XModem starts transfer, but gives ten consecutive errors on record one. Kermit just signals an error and exits. I tried both XModem CRC and XModem checksum, Any suggestions? Thanks! Anybody have experience with Amiga + Compuserve + NComm?
