I'm stumped. I'm not so sure what is the answer to that question. I'll do some research in Google and get back to you if I discover an answer. You should email the people at iPage as they probably can help you..
Can I just replace the configure.php from my last install? I think it's ok..
Will installing it again wipeout my existing mysql database?..
Create an additional temporary database and configure the install to use this, then edit your configure files to use the original database..
This will only work if you did not install any addons that modified the database. Otherwise your installation will not work until you have made the identical modifications to your new install of your final site...
I dont know if this will help, but couldn't you just overwrite all the changed php files, dont most contributions usually add tables, not convert ones being used and therefor the database should be fine to use with a new installation or without the modified php files, it would just have tables that are not used!. if you had a ftp program that could synchronise (dreamweaver, smartftp etc) with the server and just upload the changed files from an un modified 2.2??? (sorry if this is way off)..
Another way you can do it is to do a backup of your current information. Then create a temporary backup folder and copy your backup files into that temporary folder. Then after your installation, move the backup files back into your backup folder and restore the data...
I would like to install 2.2 from 2.2 because I have butchered a few of the files trying to do addons. I would like to start over without wiping out my existing MYSQL Data. How would I go about this?.
Possible, simply edit the configure.php files by hand and upload files via ftp protocol...
