Hi Kannibal

Thanks for the great program. Its been working for me on Win7 fine. I too get the "[Wed Feb 12 09:32:40 WST 2014] Error 0x1: {error:Invalid signature}" error. It seems to be occurring when I am logged into the CEX website at the same time the re investor program is running (or it could be just a co-incidence) . My log shows no errors most of the night and then I log into CEX this morning and now the error has returned. Doesnt seem to effect it doing purchases at all.

A Few suggestions to add to your program would be to

1. Export Log to CSV
2. Add selling to it. Pretty much how you have done the Buy option so a Reserve amount (Incase you want to keep BTC/NMC) , Max/Minimum price
3. Can it track your buys (ie how much its bought and whats the average price)
4. Re size the Log Window. You can re size the main Window but when you go to the log view, you cant re size that even though the main page is larger. Makes reading the log easier.

Thanks again.
