I am trying to update ~1500 old workbooks with new code. I have a
spreadsheet, ImportExport, with 13 vbext_ct_StdModule that I want to
import into the old files. It also has another standard module that
contains all of the code for the importexport routine. There are also
two text files that contain code to import into a userform and the
thisworkbook module.

Basically, the program loops through all files in a directory and all
of its subdirectories. If a spreadsheet is of the type that needs
updating, the string "version:" is in a particular cell. If the
version number next to that cell is too old, I simply pastespecial as
values the whole sheet. If it is new enough to be updated, I delete
most of the VBA code in the book, then import the vbext_ct_StdModules,
and insert the code from the two text files to the two places they
have to go. I save the workbooks and close them. Many thanks to Chip
Pearson (great name, Chip <g) for his excellent website, where I've
got a good portion of my code here from. I run the code from
Tools-Macro-Macros.

However, everytime I use InserLines for the userform or for the
Thisworkbook module, it crashes excel. A GPF or something with the
"send error to microsoft?" window pops up. Addfromstring seems to do
similarly. I've read some other posts related to this, but I haven't
seen any good definitive answer. And this code (not exactly, I forgot
what I had done to make it work, but only because I really didn't do
anything) was working and had gotten through 1000 or so workbooks the
other day. All of a sudden it started working, and working well.
Then, all of a sudden it stopped. It works on single workbooks, but I
don't want to run this 1500 times. And it crashes on the 1st or 2nd
or 3rd spreadsheet, when I run the whole thing.

Lastly, I'm sorry for the really long post, but again, this error
seems so flaky that I figured I'd give you everything I could, rather
than give you less that what you need to solve the problem. ANY help
would be hugely appreciated. I seem to be at quite the impasse here.

Just wanted to say that I got it working long enough to finish my
project. I got it to work by starting with a blank workbook and
pasting the code for the update routine into it. It seemed to run for
a few times before it would experience the same crash again, and I
seemed to be able to recreate success with starting with a blank
workbook, again. Although this isn't a good answer, hopefully someone
else will be able to use this tip if they encounter the same problem.

Thanks for your help, and sorry for the long post.
