Chronic problem! please tell me if you've experienced it. Community help!!

When playing cash games after a short period of time I can not reload if I drop below 100BB and I often will not be allowed to join another new table.

I get the error box 'Reserve Chips Failed'. With the message 'Failed to reserve chips. Please try again.'

Has anyone else experienced this? I'm getting it everyday now and struggling to play. Anyone ideas on how to fix it?
