Some install issues

[runrev at technetx.com]

Every once in a while, revolution seems to delete itself from the directory
and when I click to start it, it tries to reinstall.  It's strange.  The
only fix when it happens is I have to actually use the original
revolution.exe I downloaded to install it again, then re-enter my license
information.

Does this happen to anyone else?

Revolution 1.1.1
WindowsME

Thanks in advance,
Ron
