Tekkit Classic Server/Launcher is not working

[maxshitz]

Hi

I just got a new com this week and when i tried to play tekkit Classic the launcher says

"Java Virtual Machine Launcher"

Error: Could not create the Java Virtual Machine.

Error: A fatal exception has occurred. Program will exit.

and i don't know why this is happening then i tried to launch the server but it says

"Error occurred during initialization of VM

Could not reserve enough space for object heap

Error: Could not create the Java Virtual Machine.

Error: A fatal exception has occurred. Program will exit.

Press any key to continue . . ."

I played tekkit before on my old computer and it worked fine. I don't know whats happening?
