Can't open Data Dictionary after renaming connection

Hello Everyone.

I think this is my fault: I can’t open my Data Dictionary.

Why my fault? Because I changed my connection name, then I use Express Edit to change every single form and grid to use the new connection name… but my Data Dictionary now shows me this message every time I try to open it:

Fatal error: Call to a member function Close() on a non-object in C:\Program Files (x86)\NetMake\v8\wwwroot\scriptcase\devel\lib\php\ on line 3300

And a the log shows this:

an error occurred while connecting to the database. Connection attempt failed: invalid data source name | Script: C:\Program Files (x86)\NetMake\v8\wwwroot\scriptcase\devel\class\interface
mDataDic.class.php linha: 946

I’ve already tried to rename back my connection, or to create a new one with the old name, both cases informs me that “a connection with that name already exists”. But it isn’t shown in the connections page!! I see only the new one.

FACTS: ScriptCase 8.00.0047, MySQL 5.6.24 64 bits, on Windows 8.1 Pro 64 bits.

Can anybody help me change my Data Dict connection so I can open it again? Or suggest any other solution?
