Hi Chelsah

Workaround guide 1.1.13 might help though it looks pretty clunky

First save a copy of the file, and use it

to verify the issue by deleting windows

from the smallest dimension to the

largest, running the calculations after

each deletion until the error goes

away (note, the error is repetitive but

pressing and holding the enter key will

get past them quickly).

Once the problematic windows are

identified the issue can be resolved in

one of two ways.

1. If a precise window area is not

critical (e.g. window to wall ratio is not

close to a limit for code compliance

files) iteratively increase the window

dimensions by small increments and

run the calculations each time until the

error goes away.

2. Where window area is critical,

determine the area of the problematic

window and combine it with another

window of similar characteristics,

including orientation, to get the same

total area. As lintels and effective wall

R-values are dependent on window

width, adjust only the window height

when possible. Delete the problematic

window.

I just ran into this issue, and after a lot of experimenting, it seems H2K is acting funny with the Code Labels in the code editor.  Try renaming the code label to something more generic and then try reloading it in H2K.  Seems to be some odd combination of characters/numbers that triggers it for me with no real pattern.  Super frustrating!

The fix is to shorten the custom name.  Max 22 characters but NRCan recommends 15.

(This is a known issue and is documented in the workaround document.)
