Sequence does not work after Community edition expire in Three months

we are having a pretty bad experience. we have created a screen scrapping program that extract the data from a desktop application. program works great until uiPath expire in three month. i get the new key and uiPath start working but my program does not work any more. so i create the program again in three months. this is happening for last six months.
any one please help. client is very dis appointed and nit happy with the uipath. not sure if we are doing some thing wrong or its uiPath issue ? any one else have the same issue ?
