On my desktop, Dreamweaver reports:
Javascript Error wile loading Pure ASP Upload 3_ds.htm: Unable to open script file "Macintosh HD Applications:Adobe Dreamweaver CSS:ConfigurationataSources:ASP_JS:helper.js" (error 2).

There is no ASP_Js folder in the DataSources folder...

Seemed to happen after updating Pure ASP to the newest version.

Hello Michael Hogan.

Can you please try to clear your DW cache file?

I found the hidden Library folder, made it unhidden and deleted the cache file. The cache file was re-created when starting DW but the problem has not gone away.

What's next?

Hello Micheal Hogan and sorry for the late reply.

Did you tried to reinstall the extension after deleting the DW cache file yet?
