Ah, maybe....
Try this: If it doesn't work, email me and I've got another way...
In the 'support' folder in the acad folder, you should have a file "aclt.mns" (or somethingsomething.mns depending on what version of acad you have)
Copy this file to a disk.
On your desktop, go to the same file and rename it something like acltmns.old to back it up.
Copy your laptops .mns file to the acad support folder of your desktop.
Run acad from your desktop and it might work.....
If not, put everything back the way it was when you started, and this time, on the disk you made, rename the laptops .mns file to something like mytoolbars.mns
Put this file in your support folder
Run acad and type MENULOAD.
At the bottom of the dialog that opened, select browse and, um, browse to mytoolbars.mns and hit load.
That might work....
If it doesn't, I've got long winded way of doing it that will definitly work....
