BuildOS help: "Error Building File System"

[Matthew1034]

I just can't get BuildOS to build this ROM for my Apache. I've done several with the Titan, and it works flawlessly, but I can't get the same success with an Apache build.

Here's what I'm building:
WM 6.1 96dpi QVGA 20748_0409
Verizon
1.0 bootloader
+ Apps

Here's the last segment of the Build Status window that shows up:

Processing "_single_8.png" as file
Processing "_start_2.png" as file
Processing "_start_8.png" as file
Processing "_suite_2.png" as file
Processing "_suite_8.png" as file
Processing "__cusTSKTEMP.exe" as file
Checking IMGFS size.
Compiled Size (0x40e0000) greater than Max Rom Size (0x38e5800).
Remove 0x7fa800 bytes (8366080 bytes).

The error that then comes up is:

Error building file system

And that's it. I'm pretty much clueless about what to do, not even sure where to start troubleshooting. I searched the forums a bit and didn't find anything immediataly about "error building file system."

Any help would be greatly appreciated!
