Rollback to old driver

I have problems with my Etherlite160 after upgrading driver on my XP to the latest version (40002164_V). When I try to rollback to the original one(Digi Portserver, Date 2001-07-01, Driver version 2.0.0.0(this is MS standard driver for multiport)) it don’t work. It don’t work to “remove” the Etherlite and try to make the driver installation from the beginning either, because XP doesn’t give me the same choice as before. Now I can only choice between “Standard RealPort Device” or “have disk”, not the MS standard driver. Can you help me?

Best Regards
