CMS Made Simple Forums

I have version 1.2.3 and uploaded the 1.5.2 this a.m., overwriting the files (after backing up).  When I type in mysite.com/install/upgrades and hit enter I got a screen that tells me to choose my language.  I keep it at the default - en_US -  and when I hit enter I get the following:

Fatal error: Cannot redeclare lang() (previously declared in /home/servers/public_html/install/translation.functions.php:29) in /home/servers/public_html/lib/translation.functions.php on line 98

I next tried a new config.php file (blank) - figuring that was the problem, made sure it was chmoded to 666 - and I also tried it at 777, neither of which produced any results.

What do I need to do?

I tried reuploading all the files a third time and was finally able to gain a little progress on the upgrade, getting screens that called for checksum (which I did).  That resulted in 1 error, so I am continuing to reupload (using Filezilla) to see if I can't resolve the error.

It took multiple upload attempts, but I was finally able to get all the files recognized and continue upgrading through to completion.
