Survex 1.1.10

[asheshouse]

Hello

I've just downloaded 1.1.10 to try it out but am having problems installing.

Installed to default location c:\program files\survex

This will have installed it over a previous install (1.1.6)

When I run I get the standard MS error message "aven.exe has encountered 
a problem and needs to close"

If I re-install 1.1.6, which used to work, it gives an error message 
"cant open message file '2057' using path 'C:\program files\survex'

Operating system is Win XP Home

Any tips gratefully received.

Regards
