1. Please add better schema of your script at least.
2. Well, in step 11 above you have txtLogin = $(login), txtPassword = $(password), ...

   Can you ensure if that only misspelling in your question - or you have the same in the script?
3. Use e.g. Debug Sampler / Debug PostProcessor (inserted after both RegEx Extractors applied) to check that values for both viewstate and eventValidation were extracted from your request and your regex queries work correctly.
4. Look into the Request panel of your 2nd HTTP Request sampler in View Result Tree results to ensure that all the defined params (txtLogin, txtPassword, __VIEWSTATE, __EVENTVALIDATION) with correct values are sent along with request.
