It's a .DLL problem. Download the missing or not-working file again from here.
http://www.dll-files.com/dllindex/msvcr71.zip?0VFjSEVFkOIt's a package, so you need to unpack it with some program like winzip. Extract the file into C:\Windows\System32\ (if you're XP user) You may also put it in the Dawnspire directory.
If putting it in the system directory isn't enough, you may need to use regsvr32 by the following way:
1. Press Start and select Run
2. Type CMD and press Enter
3. Type regsvr32 MSVCR71.dll and press Enter
Hope this helps.
