Error when convert project for 15.40V from early version

[sudam_SL]

I have created project and continued with the 14.70 V and recently update the tool for the 15.40. When i have tried to open the project it required to convert it for new version and i have converted. but still i'm getting below error when i'm tiring to execute the project. are there any work around that i can convert or fix them at once. ( there are considerable amount of xpath with the variable in my project and it is taking too much time to fix one by one)

Do you still have a copy of your 14.7 version? I would try making another copy and converting it again. If you don't have it or it still doesn't work, I would contact Support directly. Here's the link
