Yu-Gi-Oh! 5D's Tag Force 6

[PaddyB10]

Hi there, I'm new to these forums.

Been playing Yugioh Tag Force 6 for a while now with no problems, but have recently run into a bug though that prevents me from advancing any further in the game. When I'm speaking with specific character(s) the text box becomes blank and I am unable press x to continue with the dialogue. I tried running the game on an older version but the problem still arises.

Also, I used the 'speed up time' hotkey a lot when playing this game, perhaps that caused it?

Strangely enough sometimes the bug occurs even earlier in the conversation, but this is seemingly random.

Any ideas? Your help would be much appreciated!
