I've
the test WDLV.dll file. Even if the last WDLV didn't work for you, this one *should*.
As with any beta file, make sure to backup your old WDLV.dll before unzipping and copying this one into your GStudio7 folder. Then run WED and create a new t7 project using the Project Wizard.
This *may* fix the error. If it doesn't, it should produce 2-3 output files that will give me better insight into what went wrong (T7ProjectManagerDebug.xml, wizardDebug.xml, and debugLogOut.xml).
Note: Even if the error goes away, if you get a file called "debugLogOut.xml" please send that to me.
