Trying to upgrade my Int'l Domino 5.0a to 5.01 but was unsuccessful. I received the following errow in the UPGRADE.LOG:
============

====================

I've download the correct incremental installer. Can't seem to figure out why.

Help.
Thanks.

For all files listed that failed the checksum, simply rename the extension of the file and try installation again. Worked for me.
