"Invalid database connection."

"Cannot establish a valid database connection
Please contact technical support."

Now, I thought I miught as well ask here before I have to call frikin technical support for this program.

That said, I have no idea what this is error is. The program was working fine before the weekend, but now whenever I go to turn it on I get that error message! I have tried uninstalling and reinstalling but that doesn't help....

Anyone know whats that matter?

Thanks iu advance

What program is giving you this error? What operating system are you using?

Program: Switched on Schoolhouse.

OS: Windows XP (pro) SP2.

Never heard of it. You may have to contact the tech support for the product. The online support section is of no help as far as I can tell.

Ah, thanks anyways

Once I figure it out I'll post the solution for it here.

Make sure MSDE is running. The program uses MSDE for the database which is Microsoft SQL Desktop Engine (I think). For some reason it may not have started.

Go to start then click on run, type in services.msc and press enter. Go through the services and make sue anything related to Microsoft SQL is turned on and set to Automatic.

Thanks so much for your instructions above. I had the same error as Celor and I followed your instructions to get MS SQL started and it worked. I no longer have the error for this Switched on Schoolhouse program and I didn't have to waste time calling tech support. THANKS MUCH!!!

SOLUTION: Use a different serial number when registering product.
I had all kinds of crazy error messages, including the "invalid data base". I had just installed my 2010 applications disk for Switched on Schoolhouse" onto my PC and was trying to install the same disk on my laptop for backup. I finally was able to when I simply used a serial number I had used last year. Then everything proceeded smoothly.

I just had that problem! i fixed it by doing the following.
#1: click the start button and got to "RUN"
#2: type in "SQLMANGR" click OK.
#3: make sure the box that says "Auto-start service when OS starts" is checked
#4: there will be a white circle above that, if it has a green triangle then reboot your system and try Switched on schoolhouse again
#5: if there is a red square or a two lines then click the green triangle button (it is just right above and to the right of the white circle) after a few moments the white circle should change so there is a green triangle in it. if so then you can exit it and restart Switched on schoolhouse and it should work. Hope this helps!
