There is not an "import" function per se. You need to pull down the version of Concrete5 that your old site used to run on, import the database into that, then go through the process of upgrading your site until you're at the desired version. This is necessary because over the years there have been database schema changes to Concrete5 and the only place that these schema changes actually get applied to the data is during the upgrade process.

Check outhttp://www.concrete5.org/documentation/how-tos/developers/manually-... for more information on upgrading.

Let me ask this...if I restore data from the removed installation, is it going to give me back the same problem I had? I wasn't able to sign in and edit because my sitemap was corrupt. That was the reason why decided to remove and start fresh. No one could give me help in getting back into edit mode to correct the sitemap.

I'm not exactly sure without knowing more about the problem. I suspect that if it truely was a problem with a corrupt sitemap, then the issue would come back with a database restore. That said I do think that your best option for recovering your data is back over on the other thread you started (http://www.concrete5.org/community/forums/usage/having-trouble-editing...cant-sign-in/). There's really a lot of data that has to be "imported" if you were going to attempt such a thing and that was only further complicated by moving to a new version of Concrete5 than you used to be on.
