E-Maculation

Whenever I attempt to open SheepShaver, it produces an error stating "Cannot map ROM: No error." and then does not start.
I assume this has something to do with the selected ROM file, but I wouldn't know exactly what since I have not modified it since setting up SheepShaver and it has worked perfectly fine before today.
I have also tried starting the emulator at different RAM sizes, but still to no success.
Any ideas on what to do to fix this?

Hi,

This is a nasty little error. You can restart your machine, and check whether you might have some programs running you could close before starting SheepShaver.
Which version are you running?

Restarting the machine worked! Curiously, terminating all other programs before starting it did not work pre-reboot, but post-reboot it now works alongside the processes that it usually should and none need to be terminated.
I am running version 2.5.

Yeah; it tries to load the ROM into memory that another program is already using. Rebooting usually clears that memory space, so SheepShaver can claim it. After it's claimed the space, other programs can load anywhere they like, since that space is already reserved.
