Needleworks,
I don't know which country you are located in, and which version of UCCNC you are running, but...
Unless you are located in USA and/or running a USA version of Windows you need to install the test UCCNC version 1.2031 because the localization is wrong in the previous versions (except 1.2030 which was withdrawn due to some serious errors).
So, perhaps if you'd install UCCNC 1.2031 the problems might go away. That is, unless you already have that version installed.
