BC,
With newer versions that HTC has put in place, some of the old maps, including the FinRus map that this WOULD have been run on, have been removed from the servers until some kind soul volunteers his time to run through the numerous checks and fixes possibly needed to allow the maps to return to servers.
In short, maps are short in supply if you hadn't noticed. This is magnified for the AvA which has a small following and would suffer from using any map larger than 256 x 256. The site that Shane pointed you to is full of great help and advice on how to do one / volunteer to help the cause. MrMidi and USRanger, with many other talented map makers share their expertise and answer question in that forum.
