"I had to move since for years that there was no updates for OpenOffice, while LibreOffice was being updated regularly and became a lot more powerful than the original source (LibreOffice is a fork of OpenOffice)."
Shouldn't it suggest plural "were"?
I won't make promises about when I can try to fix this problem.
Also, 'that' is not correct. Better:... since for years there were no updates for Open Office,...
