it would seem ubuntu is refusing to mount ANY memory pens that are fat (16/32) formatted. This used to work, but now it doesn't.

When I plug the memory pen/stick in, I get this popup

CANNOT MOUNT VOLUME.
Invalid mount option when attempting to mount the volume.

Any ideas?

try being explicit about it:
sudo mount -t vfat /dev/sdb1 /media/USB

With the drive still plugged in does dmesg | tail or sudo fdisk -l (typed at a terminal) provide any useful error messaging about the drive?

sudo fdisk -l produces this...

Disk /dev/sde: 1997 MB, 1997799424 bytes

This doesn't look like a partition table
Probably you selected the wrong device.

Partition table entries are not in disk order.

I have even re-formatted the drive in Ubuntu, and no luck, ANYTHING related to FAT is just causes an error (FAT16/32). The pen will work fine in EXT3 and everything else (even REISERFS), and automount perfectly. It's almost as though the FAT support has broken...

Did you last use it in windoze and not do a safe removal?

That doesn't look like a proper partition table. When you reformatted it, did you mkfs /dev/sde1 or did you mkfs /dev/sde ? I wonder if you formatted the drive as a filesystem rather than formatting a partition. If so, you should still be able to mount it with:
sudo mount -t vfat /dev/sde /media/USB, and probably don't even need the "-t vfat".

If that doesn't recognise it, then I suggest you repartition it with something like gparted.

yeah, when I partitioned it with GParted, anything FAT related errors out.
