This is the very first time i have had to use the forum and have had trainz from 2004 for myself and autistic son, there has been frustration in learning to get things working over the years and I decided to upgarade to 2012 but reluctantly went to download for this, progressed to fixing things and having quite a selection and had back ups and started getting some payware as son wanted to specialise, going great until this dam upgared to sp1, ages to download and go to put in , says can't find some files and aborts, when go to restart game asks for rego no, etc reput all details in and lose the bloody lot, Delete the whole lot and re instal 2012 and guess what nothing, cant install the previous rebuild , have dam files all over the place and only the basic 2012 working, son has put fist through monitor and now will spent ages going through forums and rebuilding everything again. I have given up trying the other railworks bull**** with there buying bloody everything. Went back to the more reliable trainz , what a joke. I will perservere and get it going again to the basics and then play Grand Theft Auto. Thanks a bloody lot for nothing
