Curt,

The errors you reported are from the compiler, and have nothing to do with the programmer software or 3.3v operation.

Did you re-type the errors, or copy/paste them?
They seem to be missing some characters.

In general, I would suggest this...

In MicroCode Studio, go to View > Compile and Program Options > Assembler tab.
The path above the Find buttons should show C:\Program Files\Microchip\MPASM Suite.
If it doesn't, click the "Find Manually" button and point it there.

If you can't find that folder, you'll need to install MPLAB.
Or, you can uncheck the "Use MPASM" checkbox, and it will use PM.exe instead.
