UI Path expire and does not run the sequence after reinstalling

we are using UIPath for some development and having issues. look like the license got expired after three months and when we renew it does not run our programs. i had to recreate the programs couple of times.
from developer perspective UIPath look very unstable. can you please help to sort out the issue.

What error you are getting?

Please check this link to renew your free license:

There is no error. my program scrap a screen and save data in the file. it just stop scrapping the screen.
this is third time it happens. every time, i renew i have to re create the whole program. is this happening to others or just me ? i am not confident if i do some major work in uiPath if will be stable.
