Atrix 4 with Flash downloaded not working anymore

[Crayon57]

Have an Atrix 4G. Flash worked fine until gingerbread update. Now it works "sometimes" at the same site (such as YouTube) but most of the time doesn't work when an app says I need to install Flash. I've even updated Flash to the latest version. No help. Do I need to wait for ice cream sandwich or is there a fix for this?
Thx in advance!
