Good day to Vegas forum

Now I am having a tough problems that is almost unsolvable. I tried to change font style in the credit roll's editing window and I saw that the rest part is cut off making me not able to click the missing place, which used to be exist. I cannot finish the credit roll. Do you guys know how to get it back?

Here's what I've already tried:

1. I tried changing windows display resolution from 1980x1080 to many resolutions and I did not work at all.

2. I tried changing the "MS Sans Serif 8,10,12,14,18,24" font value in registry from "SSERIFE.FON" to "SSERIFER.FON." I restarted my computer, cleared cache, opened the editing window, and it also did not work.

Please help me because this is the documentary video for my and my friend's high school grade. 😭
