Hi Hima Sailaja,
No, there is no limit to code conversion in the fully licensed software. We only see this behavior when the software has not been licensed. That makes me believe the activation did not work properly as it should have.
When you start Visual Studio are you prompted to activate every time? You shouldn't. Once activated, it should stay activated and you should not be prompted again (uniless you uninstall and re-install... uninstall will deactivate it on that machine).
Please try running Visual Studio as Administrator by right clicking on it in your Start Menu and selecting "Run as administrator". Let us know if that helps.
All the best,
the Telerik team
