Pointshop doesn't work for me =(

[nezdude]

Hello, i recently started playing TTT and the server i like to frequent has the pointshop installed. Typically though, it doesn't work for me for some stupid reason that i can't figure out =( when i press F4, which is the bound key, a blank box pops up where the shop should be, and a little lua error pops up on the right hand side, which says:

[cl_pointshop.lua:135] attempt to index field 'Config' (a nil value)

i looked in the cl_pointshop.lua and there doesn't even seem to be a reference to Config XD

any help would be much appreciated

EDIT: Solved with reinstall of Gmod XD
