Hello All,I purchased activity master a few weeks ago and finally gave it a go today,I watched the videos ,which are a great resource for us newbies.
I downloaded the kodachrome yrs act. loaded it into activity master, went to replace the rolling stock and engines hit the replace button and got error 55 runtime.
What did I do wrong,or is something else going on????Thanks Dave
sorry to hear about the virus

I'm not sure what error 55 is, I THINK it might be "file already open".  Since you purchased and downloaded ActivityMaster a few weeks ago, could you try downloading the update/patch from the Patches & Updates page and see if this fixes the problem?

If not, I'll need you to tell me a little more about what the error message says.

Thanks and sorry about the problem,

Steve Davis
