Reinstalling wine won't help; the problem is with your configuration settings.
The easiest way to reset it to the defaults is:
Code:
mv ~/.wine{,.backup}
wineboot
The first command renames your .wine directory to .wine.backup (in case you want to get it back), the second will force creation of a new .wine directory. You will then have to reinstall your program(s).
A safer way to get msvcrt.dll is with winetricks: http://wiki.winehq.org/winetricks
