problem setting grid on localhost

Hello,
Upgrading my 2.5 site to Joomla 3. Had Tools JX working well in 2.5 production site. Now developing my Joomla 3 site on my localhost (Server:localhost:8889). Just bought ToolsJX for Joomla 3 and installed fine. Go to set grid and Connection: other, mysql, localhost:8889, Database User:, PW; Database Name: Similies and click on Check and List Tables, and it says it cannot find Database.

Not sure what doing wrong. I created the database Similies with MAMP. Imported same table.cvs and it seems to be there with the data. Using my User Name and PW I use to login to my localhost site. When I go to my developing site I use localhost:8888 but the database has it as localhost:8889. I have tried both but neither work when I click on Check and List Tables.

Thanks,
To

Thanks for the help. I think I have moved one step forward. I'm now logging in with MAMP connection parameters they give: localhost; 8889; root; root. This works when I use localhost or localhost:8889. I click on Check and List Tables and it does not kick me back to Control Panel and takes me to the next choice. In Table Settings I click on Select Table and Table 1 is there as it should be. But if I select Table 1, now it kicks me out and sends me back to Control Panel.

I can't think of what is wrong here and hoping for guidance.
Thanks.

It was named TABLE 1 and I renamed it to TABLE1. Now it shows Table 1 and Table1 in the select box, but the same problem happens if I click on TABLE1.
I think I'll just wait until I go live. Maybe it will work again as it was before.
P.S. There is a Database in the folder called mysql. I created another called Similies. It has one table which is now called TABLE1. -- If that is the problem, please let me know. Otherwise I'll just wait and try again live.

Thanks,
Tom
